JFETs are, almost invariably, depletion mode devices, which means that there will be some drain current at a zero-applied gate-source potential. This current will decrease in a fairly linear manner as ...

A Class D audio amplifier is a switching amplifier that consists of a pulse width modulator (with switching frequency in the order of several hundred kHz), a power bridge circuit and a low pass filter ...

Abstract: This paper presents a novel narrow-band amplifier model designed to amplify small signal inputs effectively. These signal amplifications are required in audio range signal excursions and in ...
