Abstract
A track and hold circuit () comprising a switch device () and a capacitive hold device (). The track and hold circuit () comprises a track-voltage generating device () adapted to generate a control voltage based on a signal on an input terminal of the switch device () and supply the control voltage to the switch device () during track phases of the track and hold circuit (). The control voltage provides a channel charge, which is the same for each track phase, in the switch device ().
