ABSTRACT:
In a differential amplifier comprising a pair of transistors, these transistors comprise first and second MIS type field effect transistors with their gate electrode connected to a source through load resistors or MIS transistors, drain electrodes connected to input terminals respectively through serially connected capacitors and MIS type field effect transistors and source electrodes commonly connected to a source of constant current. One ends of the capacitors on the side of the input terminals are connected to the current source and the other ends of the capacitors are respectively connected to the drain electrodes of the pair of transistors through MIS transistors.
