Abstract
A feedback circuit for passing uniformly constant current relative to cha storing devices is disclosed. An open circuit is disposed between two terminals in a feedback loop and these terminals are interconnected through the charge storing devices to close the open circuit, when the uniformly constant current is to-flow for the purpose of either charging or discharging such devices. The feedback loop is included in a voltage regulator which in the preferred embodiments, is comprised only of an operational amplifier and a resistance.
