Abstract: This invention pertains to a source follower circuit suitable for receiving and buffering an input voltage and providing the buffered input voltage to a sampling capacitor via a sampling switch. The source follower circuit employs a slew enhancement circuit which enables the source follower to have fast settling for both high-to-low and low-to-high transitions.
