Using my Multisim SPICE tool to analyze an oscillator, I ran into a little bit of simulation trouble. My circuit was a simple Colpitts oscillator and the simulation showed that it would indeed ...

Some of the commentary in response to Part 1 on this topic suggested that the two 1 pF capacitors, C4 and C5, had to be put in series for lack of availability of 0.5 pF parts. A simulation of that ...

Noise is a fact of life, especially in electronic circuits. But on our paper schematics and just as often our simulations, there is no noise. If you are blinking an LED on a breadboard, you probably ...
