ABSTRACT:
A sample hold circuit includes an op-amp, first capacitors provided on an inverting side of the op-amp and second capacitors provided on a non-inverting side. The sample hold circuit is configured such that a total capacitance of the first and second capacitors to which an input voltage is applied in a sampling phase is equal to that of the first and second capacitors to which the input voltage is applied in a holding phase, a total capacitance of the first capacitors to which the input voltage is applied in the holding phase is equal to that of the second capacitors to which the input voltage is applied in the holding phase, and a total capacitance of the first capacitors to which the input voltage is applied in the sampling phase is different from that of the second capacitors to which the input voltage is applied in the sampling phase.
