Description

ABSTRACT:
An analog input voltage is inputted to a first sample and hold circuit and a second sample and hold circuit is connected to an output of the first sample and hold circuit. The output of the first and second sample and hold circuits are inputted to a multiplexer which alternatively outputs the output of first sample and hold circuit or the second sample and hold circuit. When one of the first and second sample and hold circuits is refreshed, the output of the other sample and hold circuit is selected to be outputted from the multiplexer.
