ABSTRACT:
A circuit and method for performing track and hold operations utilizes a circuit configuration in which a hold capacitor connected to a track signal path can be selectively isolated from an input signal applied to a control device on a common signal path by a switching mechanism, which is used to switch the circuit between track and hold modes of operation. The switching mechanism operates to connect either the track signal path or a hold signal path to the common signal path. When the track signal path is connected to the common signal path, electrical charge is allowed to be stored in the hold capacitor. When the hold signal path is connected to the common signal path, the hold capacitor is electrically isolated to hold the stored electrical charge.
