Many people who get analog electronics still struggle a bit to design oscillators. Even common simulators often need a trick to simulate some oscillating circuits. The Barkhausen criteria state that ...

Designers can take advantage of the latest fabrication techniques for and the expanding array of materials used in nonlinear devices (see “Use Nonlinear Devices As Linchpins To Next-Generation Design, ...

Various configurations (Colpitts, Pierce, Clapp etc) are described in literature [Ref(1)]. Depending on the frequency requirements, various devices like MESFETs, pHEMTs, and HBTs can be used for VCO ...

Despite being well documented, nonlinearity—its theory and applications—is often viewed as a novelty or strange anomaly. Here, we’ll argue the opposite point of view. Nonlinear and negative ...

Try an experiment. Next time you are in a room with someone, ask them to name everything in the room. Only certain kinds of people will say “air” or “light.” For most people, those are just givens, ...
