Abstract
A double switched track-and-hold circuit includes an input buffer having a first switched amplifier circuit for passing an input signal in a track mode and isolating the input signal from a buffer output in a hold mode, and a track-and-hold core circuit responsive to the input buffer and having a second switched amplifier circuit for tracking the input signal in a track mode and isolating the input signal from a track-and-hold output in a hold mode. The first and second switching amplifier circuits turn off approximately simultaneously during the hold mode to provide enhanced isolation.
