Abstract
A sample/hold circuit which receives a voltage level at the input terminal thereof at a specific timing, and outputs the received voltage level in the form of a hold voltage. The sample/hold circuit includes an analog-to-digital converter for receiving a voltage level at the input terminal thereof, a memory element for storing the received voltage level in the form of hold voltage data, and a digital-to-analog converter for outputting the hold voltage data. The sample/hold circuit may be fabricated into a one-chip integrated circuit. The memory element may be a nonvolatile and reprogrammable memory.
