Last time on Circuit VR, we looked at creating a very simple common emitter amplifier, but we didn’t talk about how to select the capacitor values, or much about why we wanted them. We are going to ...
Did you know that you can use LTspice to do Digital Signal Processing (DSP)? Actually, I should say it is useful for validating the operation of a signal-processing algorithm under development. This ...
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 ...
