ABSTRACT:
A circuit which can be used to hold either the maximum or minimum voltage applied. A comparator compares the input voltage to the previous high or low and a set of two mirror circuits either charge or discharge a holding copacitor to the new value. A control circuit of transistor switches configures the circuit into either a maximum or minimum holding mode.
