Inverter circuit

Abstract

Abstract PURPOSE:To obtain an inverter with fast response speed even to an input voltage changing slowly by using a low voltage when the input voltage rises and using a high voltage when falling as a reference voltage so as to apply inversion. CONSTITUTION:A voltage shifting an input voltage VIN by a threshold voltage of an NMOSFET Q11 and a PMOSFET Q12 appears at the output terminal of a voltage shift circuit 12. A mirror type differential amplifier circuit 13 compares the input voltage VIN with a voltage V1 of a reference voltage terminal, the input voltage VIN is inverted at a point when the quantity of the values is inverted to obtain an output voltage VOUT of the inverter circuit. Thus, the inverter circuit provided with the differential amplifier circuit obtaining an output voltage corresponding to the input voltage is obtained.
