ABSTRACT:
An integrated circuit for rapidly charging a capacitive holding device to a voltage level within a predetermined range of acquired samples. One or more supercharging circuits can be provided to supplement the input signal in charging the signal holding device when the input signal by itself is not capable of providing enough current for rapid operation. The supercharging circuits compare the input signal with the held signal and provide supplemental charging current when the differential between these signals exceeds a predetermined threshold amount. Above this threshold the supplemental charging current varies progressively and preferably linearly with the signal differential, until a terminal point is reached above which the supercharging current remains constant. Provision is also made for inhibiting leakage of the held signal back into the charging circuit.
