Ratings and Reviews

Better simulator than exploriments

Love this app cos you can learn the basics and a little more unlike the exploriments which is boring and obsolete after one use..please let us a chance to perform more open and not scripted experiments.

I had to come back and write this after a couple of days use, this app has thought me a lot and I will pay if you can add more components and complications so it can be fun for us wannabe engineers (solar panel inverter) etc so we can do some rough calculation in an exciting way.... Thank you for this app

Just missing one small thing

This is a great app but I fell it needs one more thing: transformers. I want to make a certain circuit but it needs a transformer. That’s the only one thing I would change

Fantastic

If you are stuck on circuits and you need help, this is the app for you. This app is very helpful and it is very easy to use. I recommend to everyone who is dealing with difficulties on circuits. This is a great app!!!

Device models

The simulator has simple models for semiconductor devices (diode, bjt, mosfet) and two operational amplifiers. Each model has just a few adjustable parameters. For more sophisticated simulations, check out the other circuit simulator resources mentioned below.

The simulator’s solver a technique called Modified Nodal Analysis (MNA), based on the application of Kirchhoff’s Current Law. (Whereas the SPICE simulator is based on Kirchhoff’s Voltage Law.)

Diode model

Circuit Online circuit maker diode symbol

The default saturation current is $\text I_\text s = 1.0\times 10^{-14}$ ampere.
The Area parameter scales the saturation current to Area $\times \,\text I_\text s$.

MOSFET model

Circuit Sandbox nmos fet symbol$\quad$ Circuit Sandbox pmos fet symbol

N-type and P-type MOSFETs

The MOSFET model in Circuit Sandbox is the quadratic model. The Linear region is modeled by a quadratic equation, $aV_{DS}^2 + bV_{DS} + c = 0$, described below. Another feature is the parameter ($\lambda$) that models the resistance of the drain-to-source current path.

Fixed parameters
$\mu C_{ox} = 20 \times 10^{-6} \,\text{A/V}^2 = 20\,\mu \text{A/V}^2\quad$ (SPICE parameter KP)

Adjustable parameters
$W/L$ is the area of the device. The default value is $2$.

$V_T$ is the threshold voltage (positive for both N and P types) (SPICE parameter VT0).
The default value is $0.5\,\text V$. When $V_{GS}$ is less than $V_T$ the drain current $I_D$ is $0$.

$\lambda$ is channel-length modulation (SPICE parameter LAMBDA).
The default value is $0.05\,\text V^{-1}$, $1/\lambda = 20\,\text V$. Lambda ($\lambda$) together with $I_D$ determines the small signal output resistance (the upward tilt of the lines in the saturation region),

$r_D = \dfrac{1}{\lambda I_D}\quad$

Cut off region, $V_{GS} \leq V_T$

$I_{D} = 0$

Linear (Non-saturation) region, $V_{GS} > V_T$ and $V_{DS} < (V_{GS} - V_T)$

$I_D = \mu C_{ox} \dfrac{W}{L} \left [ V_{GS} - V_T - \dfrac{V_{DS}}{2}\right] V_{DS} \,(1 + \lambda V_{DS})$

Saturation region, $V_{GS} > V_T$ and $V_{DS} > (V_{GS} - V_T)$

$I_{D} = \mu C_{ox} \dfrac{W}{L} \left [ \dfrac{(V_{GS} - CyberLink YouCam Free Activate \right] (1 + \lambda V_{DS})$

Boundary between Linear and Saturation regions

The MOSFET’s behavior changes from Linear and Saturation when $V_{DS} = (V_{GS} - V_T)$. This is the point where the two online circuit maker for drain current intersect. That drain current is,

$I_D = \mu C_{ox} \dfrac{W}{L} \dfrac{(V_{DS})^2}{2}\quad$ or $\quad I_D = \mu C_{ox} \dfrac{W}{L} \dfrac{(V_{GS}-V_T)^2}{2}$

This is the rising parabola in the graph.

The defining ReFX Nexus VST 3.4.4 Crack + License Key 2021 - Activators Patch for the opamp is: $(\sf{vo} - \sf{vg}) = \text A(\sf v$+ $\,- \,\,\sf v$-$)$

The default gain is $\text A = 30{,}000$. You can change it to anything you want. If the input voltages are identical then the output voltage will be $\sf{vg}$. To simulate symmetric power supply voltages, connect $\sf{vg}$ to ground. To simulate a single-sided power supply (one side is ground, the other is $\text{+Vs}$) set $\sf{vg}$ to $\text{Vs}/2$. It is your responsibility to make sure $\sf{vo}$ stays between the power rails.

System information

The circuit sandbox works best on a desktop or laptop computer where you have plenty of viewing area. You can also use it on a tablet. (It works on smart phone, too, but the experience is a bit awkward because the screen is so small.) It should work seamlessly in most modern browsers under Windows, Mac, and Linux. If you experience problems, please let me know.

Your circuit is never transferred to the Spinning Numbers web server.

Desktop/laptop

A quick way to save your circuit is to click on the link icon. It displays a big URL you can copy and paste wherever you want. Paste it into a browser to recreate the circuit.

The save icon saves the circuit to the Download folder on your computer in JSON format (JavaScript Object Notation). The file is named ckt.txt.

The open icon loads a circuit from your computer’s file system.

If you want to keep your work be sure to save your circuit before leaving the web page.

Touch devices

If you have a touch device (tablet or smart phone),

  • One finger selects a component or drags a selection rectangle

Tablet

On a tablet you can save one circuit file. When you save a circuit, it is tucked into a memory area inside your browser. When you open the saved circuit, the circuit file is retrieved from browser memory. If you want to keep your work, be sure to save before leaving the web page.

Mobile devices

The simulator works on a smart phone, but the display is a bit small for drawing schematics. You can save and load one circuit file, the same as for a tablet.

Configure

Circuit Sandbox accepts a few extra parameters to customize the parts bin and analysis choices. You can do this with either the URL or the html <input> statement. Here is an example of a URL with a limited parts bin and analysis choices,

A URL parameter list starts with a ? question mark. Each parameter is separated by an & ampersand character. Notice there are no quote marks.

You can also provide an initial schematic. Draw up a circuit and grab the URL with the link. The circuit JSON is captured in the value parameter. Append the part and analysis options separated by ampersands,

Circuit Sandbox encodes URL links so they survive trips through email. This same link looks like this when encoded,

You can also initialize a schematic if you call Circuit Sandbox from an html <input> statement—this time with quotes,

Your choices for analyses are dc, ac, and tran.

Here are your part choices, simlab composer pro - Activators Patch part has a one-letter name,

Translation

Want to help translate the Circuit Sandbox into other languages? That would be great! If you are fluent in English and another language, especially the technical terms used in the simulator, I could really use your help. Contact me by email and I will provide a table of about 170 terms and phrases for you to translate.

The Circuit Sandbox was created at MIT

The Circuit Sandbox was written in 2011 for MIT 6.002x, the very first massively-open-online class (MOOC). Professor Chris Terman wrote the schematic capture module and Professor Jacob White created the simulation engine based on Modified Nodal Analysis (MNA). MIT transferred Circuit Sandbox to EdX in 2012. I made improvements to the simulator while a Content Fellow at Khan Academy in 2016 and since then.

Circuit Sandbox includes schematic capture and a circuit simulation engine. It is not a version of SPICE. It is its own interpretation of a circuit simulator written in 100% Javascript. It does not require installation—just click on the link and the simulator opens, ready to run.

Other circuit simulators

The granddaddy of all circuit simulation programs is SPICE (Simulation Program with Integrated Circuit Emphasis). This program was created at the University of California, Berkeley in the 1970’s. It was originally written in FORTRAN. SPICE has always been in the public domain. It is one of the jewels of human creativity.

The input to SPICE ESSS Rocky DEM Licenses key a plain-text circuit description (a SPICE netlist). SPICE is the workhorse of the electronics industry because it supports sophisticated models for semiconductor devices (diodes and many types of transistors).

Many people have wrapped front-end interfaces around SPICE to allow designers to draw a schematic and automatically create SPICE netlists. The text netlist is submitted to SPICE for simulation. The results come back and you can plot them. Many of these packages can be found by searching the web for “circuit simulator.”

An excellent version of SPICE is available from Linear Technology, a semiconductor manufacturing company in Milpitas, California. The program is LTSpice (from linear.com) or LTSpice (from analog.com). LTSpice runs on Windows, Macintosh, and Linux machines with Windows emulation. It is free to download and use.

Note: Linear Technologies was purchased by Analog Devices in 2017. The web sites have been merged together.

Another simulator is JADE. It’s a follow-on to Circuit Sandbox with improved features for digital design and logic simulation. Here’s an intro video.
