ABSTRACT:
A circuit design incorporates charge compensation devices within a Track-and-Hold (T/H) circuit to control channel charge generated by a tracking switch. Calibrating a T/H circuit requires selecting charge compensation devices from an array of similar devices to function within the T/H circuit to absorb charge ejected from the tracking switch. The charge compensation devices can also be pseudorandomly selected to operate within the T/H circuit. Charge compensation devices are used to enhance the performance of bottom-plate sampling systems as well as bootstrapped T/H circuits.
