Abstract
In an NOR logic circuit employing an MES (Metal Semiconductor Junction) field effect transistors, an MES field effect transistor 2 for driving an output stage operates in response to an input signal applied to an input terminal 101 or 102 to output an output signal from an output terminal 200. In this operation, an MES field effect transistor 4 for pull-down of input operates in response to an output signal fed back by a feedback circuit comprising a diode 5 and a current power supply transistor 3 to charge and discharge the gate of the transistor 2. Therefore, the transistor 2 can operate promptly and, as a result, the logic circuit can be operated at a high operating speed.
