Abstract

Sample-hold circuit for having small droop rate, and short acquisition time, with high-speed, is provided. For this aim, a D/A converter for outputting a neighborhood voltage of input voltage, a subtracter outputting the difference of the output voltage of the D/A converter and the input voltage of the subtracter, and an adder for adding the hold voltage of the sample-hold means and the output voltage of the sample-hold means and the output voltage of the D/A converter, is provided.
