NON-DRIFTING HOLD-AMPLIFIER

A method and apparatus for controlling a process wherein a hold amplifier is used to maintain the charge on a capacitor, the charge on the capacitor representing the desired position of a control element. The charge on the capacitor is maintained by periodically connecting it to a reference voltage.
