Abstract
This paper describes a monolithic sample and hold circuit with performance competitive with state of the art hybrid systems. It is based on a differential amplifier with gain of unity, which has a feedback loop in the hold mode to ideally get a droop rate of zero. The outstanding electrical characteristics of this S&H - circuit are the 120 MHz 3- dB bandwidth and an acquisition time of only 12 ns.
