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 … WebThe source follower circuit is used as a voltage buffer and level shifter. It is more flexible level shifter as the dc value of voltage level can be adjusted by changing aspect ratio of MOSFETs. It is desired to have low output resistance for such applications. Source follower can give minimum output resistance 1/(gm+gmb) with load resistance and …
WebAug 25, 2012 · A grounded source configuration would be the usual choice to mimic a pentode. Using a source follower will likely just give the sound of the driver/gain stage instead. The power law transfer function of Mosfets changes from square law thru 3/2 power law toward linear law as the current thru them increases.
WebJan 21, 2009 · A source follower circuit is disclosed with an added amplifier that extends the low input voltage linear range while providing a lower output impedance. The drain of the source follower MOSFET is coupled to a gain stage that drives a second MOSFET (or other type transistor) with its drain coupled to the follower output. High impedance … free irisWebA unity gain buffer amplifier may be constructed by applying a full series negative feedback (Fig. 2) to an op-amp simply by connecting its output to its inverting input, and connecting the signal source to the non-inverting input (Fig. 3).
