Abstract
The track-and-hold circuit includes a switching circuit and a plurality of storage devices. The switching circuit responsive to an input signal applies a representation of the input signal to the storage devices in a track mode and blocks a signal path between the input signal and the storage device in a hold mode such that a transition from the track mode to a hold mode causes the storage devices to store a time sample of the input signal. An acquisition glitch suppression circuit includes a replica amplifier coupled to the switching circuit that senses a differential voltage across the storage devices. A switched clamping circuit clamps inputs of the switching circuit to the sensed differential voltage in the hold mode such that the initial condition of switching transistors of the switching circuit are approximately identical prior to a hold-to-track transition to mitigate differential acquisition glitch.
