Two of the most often used amplifier building blocks in audio amplifier design are the common emitter amplifier with emitter degeneration and the emitter follower using the same circuit biasing. The ...

Most buffer amplifiers use some kind of “follower” circuit such as a BJT or a MOS in a common-collector or common-drain configuration. Such transistors, however, have a finite transconductance (gm) ...

Large analog systems that present many loads to a voltage-reference source can often demand more current than a single reference IC can deliver. However, if the reference IC includes force and sense ...

Sometimes, the need arises fora low-distortion buffer amplifiercapable of handling bipolar signals. Youcan use an op amp or integrated bufferfor these applications, but for more flexibility,a discrete ...
