Voltage Follower

Some articles on follower, voltage follower, voltage:

Common Drain
... 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 ... Thévenin resistance of a combination of a voltage follower driven by a voltage source with high Thévenin resistance is reduced to only the output resistance of the voltage follower (a small resistance) ... That resistance reduction makes the combination a more ideal voltage source ...
Common Collector - Applications
... impedance to drive a small load impedance it functions as a voltage buffer ... on the hFE of the transistor) instead of voltage gain ... the Thévenin resistance of a combination of a voltage follower driven by a voltage source with high Thevenin resistance is reduced to only the output ...
Implementations - Current Sources With Negative Feedback
... They are implemented as a voltage follower with series negative feedback driven by a constant input voltage source (i.e ... a negative feedback voltage stabilizer) ... The voltage follower is loaded by a constant (current sensing) resistor acting as a simple current-to-voltage converter connected in the feedback loop ...
