ABSTRACT:
A semiconductor integrated circuit device of a type wherein loads for source follower amplifiers FETs whose gates receive an amplified signal produced from a differential amplifier section and whose each source generates an output signal, comprise first load FETs whose each gate area is small and second load FETs which are respectively series-connected with the first load FETs, whose each gate length is relatively long and each of which has small drain conductance.
