The power stage of switching converters can be modeled essentially as a PWM-switch. A switch seems to be far from the kind of circuit element that can be linearized, but it can be. This Part 2 ...

A little over a year ago, I had a project that required driving an RF single-pole double-throw (SPDT) coaxial switch either by transistor-transistor-logic (TTL) pulses sent by an external source or by ...

This simple circuit is a line-level audio signal muting switch based on a soft-action power on/off process. When the S1 switch is closed, R4, C1 and Q4 JFET quietly ground the signal to be muted in ...

Thermocouples and their leads often have to detect open-circuit or short-circuit faults. However, it is very difficult to distinguish a valid millivolt temperature signal from an open/short-circuited ...
