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 ...

In the previous part of this series, we had discussed some of the important specifications of a crystal such as crystal pulling range, drive level and crystal stability with respect to temperature ...
