What is Ltspice: Definition and 54 Discussions

LTspice is a SPICE-based analog electronic circuit simulator computer software, produced by semiconductor manufacturer Analog Devices (originally by Linear Technology). It is the most widely distributed and used SPICE software in the industry. Though it is freeware, LTspice is not artificially restricted to limit its capabilities (no feature limits, no node limits, no component limits, no subcircuit limits).

    How Do You Add a New Diode Model in LTspice?

    EDIT: PROBLEM SOLVED! I found a model on a website of the manufacturer! Next, I need to hunt down this 5.1 V Zener. Hey. I'm designing a full-wave bridge rectifier regulated by a Zener, and on of the project requirements is an LTspice simulation(not to mention it's a good place to start before...

    LTSpice question, dependent sources.

    I use LTSpice, and vaguely remember there was a way to make a voltage (or current) source depend on either another source in the circuit, or to follow some function of time. I think it's either a source parameter, or a command line placed in the schematic. Does anybody know how to do this...
