We always enjoy [FesZ’s] videos, and his latest about FREQ function in LTSpice is no exception. In fact, LTSpice doesn’t document it, but it is part of the underlying Spice system. So, of course, you ...

LTspice simulation of the K2-W Vacuum Tube Op Amp’s design reveals the mad science that created a commercial revolution in 1950s and 1960s analog computing. The K2-W's first-stage differencing ...

This article describes how LTspice simulations can be used to account for the effect of voltage dependence, or dc bias, caused by the use of ceramic capacitors with smaller and smaller case sizes.

An approach to design custom PWM filters using a visual basic application spreadsheet automatically launch a simulation to ...
