In electronics, a common-drain amplifier, also known as a source follower, is one of three basic single-stage field-effect transistor (FET) amplifier topologies, typically used as a voltage buffer. In this circuit (NMOS) the gate terminal of the transistor serves as the signal input, the source is the output, and the drain is common to both (input and output), hence its name. The analogous bipolar junction transistor circuit is the common-collector amplifier. This circuit is also commonly called a … WebJul 1, 2012 · Conventionally, source followers have been used at the block of track-and-hold amplifiers (THA) for high-speed medium-bit analog-to-digital converters (ADCs). … healing quest wellness center
