Circuit Simulator Applet

Circuit Simulator Applet
This is an electronic circuit simulator. When the applet starts up you will see an animated schematic of a simple LRC circuit. The green color indicates positive voltage. The gray color indicates ground. A red color indicates negative voltage. The moving yellow dots indicate current. To turn a switch on or off, just click on it. The "Circuits" menu contains a lot of sample circuits for you to try. Full Screen version. Directions. Index of Circuit Examples. More applets. Javascript version. Report a problem/feature request Huge thanks to Iain Sharp for the Javascript port.

Subcircuits Page Device Models, & Subcircuits 10-BIT DAC (Behavioral) Subcircuit (with PSpice & LTspice Symbols) When you are designing a system at the device level (transistors, resistors, etc.), it's convenient (and speedy) to represent some subsystems behaviorally while you wring out other system components, e.g. a successive approximation register. Thus I threw this 10-Bit DAC behavioral model together... trivial actually, but saved me tons of time. I have now made this a fully parameterized subcircuit with VFS (full-scale-output), VH (high logic level) and VL (low logic level) selectable by the user.

The 555 can be used to provide time delays, as an oscillator, and as a flip-flop element. Derivatives provide up to four timing circuits in one package. Introduced in 1971 by Signetics, the 555 is still in widespread use due to its ease of use, low price, and stability.

OrCAD Downloads OrCAD 16.6 Lite Demo Software (All Products) Designers around the world rely on the powerful yet intuitive OrCAD® personal productivity tools. OrCAD has a long history of providing individuals and teams with a complete set of technologies that offer unprecedented productivity, seamless tool integration, and exceptional value—the OrCAD 16.6 release continues with that tradition. Operational amplifier applications This article illustrates some typical applications of operational amplifiers. A simplified schematic notation is used, and the reader is reminded that many details such as device selection and power supply connections are not shown. Operational amplifiers are optimised for use with negative feedback, and this article discusses only negative-feedback applications. When positive feedback is required, a comparator is usually more appropriate. See Comparator applications for further information.

555 Timer/Oscillator Tutorial © by Tony van Roon Thank you Ron Harrison from Micron Technology, Inc. for pointing out the errors in this tutorial! The 555 timer IC was first introduced around 1971 by the Signetics Corporation as the SE555/NE555 and was called "The IC Time Machine" and was also the very first and only commercial timer ic available.
