Abstract:
A semiconductor integrated circuit in whicha plurality of circuit units each of which is constructed in a manner such that a gate of an insulating gate type transistor is connected to a signal input terminal through a first capacitance, a common connecting point serving as a floating point of said gate and said first capacitance is connected to one terminal side of a second capacitance, and a controller, arranged to fluctuate a voltage on the other terminal side of said second capacitance so as to further increase or decrease the drain current of said insulating gate type transistor in correspondence to an increase or decrease of said drain current of said insulating gate type transistor is connected between a drain of said insulating gate type transistor and the other terminal side of said second capacitance are provided, andsources of said insulating gate type transistors of said plurality of circuit units are commonly connected and are connected to a constant current source,wherein each of said circuit units constructs a positive feedback loop for further increasing or decreasing said drain current in accordance with an increase or decrease of a source current of said insulating gate type transistor.
