ABSTRACT:
A sample-and-hold circuit configured with a low source voltage for assuring low power consumption. An input signal and an output signal are coupled to one side and to the other side of a current mirror circuit. The input signal is sample-held by a differential circuit adapted to cause the current to flow a desired current to the current mirror circuit and to perform switching of the current mirror circuit and sample clocks entered to the differential circuit. The sample-holding operation is feasible even with a lower voltage source.
