Abstract
Presented herein is a three-state buffer circuit having a voltage follower for directly driving a sampling capacitor at an output terminal of the three-state buffer circuit. The three-state buffer circuit further includes a switched capacitor circuit connected at an input of the voltage follower and configured to control the voltage follower to operate in one of a plurality of states. The states are: a tracking state, at which the voltage follower is configured to provide an output voltage at the output terminal at a level corresponding to an input voltage at an input terminal of the three-state buffer circuit; a hold state, at which the voltage follower is configured not to provide any output voltage at the output terminal; and a reset state at which the voltage follower is configured to provide an output voltage at the output terminal at a reset voltage.
