Abstract
A track and hold amplifier is provided. The track and hold amplifier includes an input node receiving an analog signal, a buffer coupled between a first node and an output node, a first switch coupled between the input node and the first node, a plurality of switching circuits and a voltage generating unit. Each of the switching circuits includes a capacitor coupled between the first node and a second node. The voltage generating unit selectively provides a common signal or a reference signal to the capacitors of the switching circuits, wherein the reference signal is independent from the analog signal.
