A bipolar junction transistor (BJT) is a device that can amplify signals thanks to its two p-n junctions and three terminals: base, collector and emitter. This device is operated by current. At the ...

Abstract: Cascode amplifiers have three configurations: bipolar junction transistor-bipolar junction transistor (BJT-BJT), field-effect transistor (FET)-BJT, and FET-FET. Although the high-frequency ...

The transistor and the PWM-switch, the core circuit of power converters, have interesting analogs. Both have three terminals, hence three configurations. They are active devices, and each has a key ...

An Amplifier is an electronic circuit designed to increase the strength of a weak input signal in terms of voltage, current, or power. This process is called Amplification. Couples the AC signal to ...

This article goes through the circuit analysis of a generalized single-transistor amplifier for the purpose of finding the open-circuit time constants (OCTCs) of the two BJT capacitances. The ...
