Over the recent weeks here at Hackaday, we’ve been taking a look at the humble transistor. In a series whose impetus came from a friend musing upon his students arriving with highly developed ...

Many PWM (pulse-width-modulated) applications, such as Class D audio amplifiers, require symmetric drive circuitry. Comprising complementary N- and P-channel FET devices with gates and sources ...

FET constant current sources use JFETs and MOSFETs to deliver a load current, which remains constant despite changes in load resistance or supply voltage. A FET constant current source is a type of ...

Unlike power switching FETs, RF FETs are designed to work best in the linear region of operation to maximize power gain and minimize distortion, whereas power switching devices are optimized for ...
