This article continues from a previous one, “Bandwidth from Transfer Functions” to consider some aspects of frequency response above bandwidth. These include approximation of the unity-gain frequency ...

The specification of load current transient response at the output of a power supply is subject to requirements related not only to the load transient demand itself—specifically load current step ...

Closed-loop control systems are sometimes shipped from the factory with resonances and other operational difficulties that aren't supposed to be part of the package and are not well understood.

It is a familiar situation. An application needs an amplifier with excellent output drive capability, say several hundred milliamps, to drive a large capacitive load. The supplier’s engineering team ...
