PURPOSE:To reduce the voltage consumption, by making the first and the second insulated FETs conductive and non-conductive respectively by complementary input signals and by operating the third and the fourth insulated FETs between a prescribed power source voltage and the earth voltage. CONSTITUTION:When complementary input signals of -V and 0 are applied to gate electrodes of FETs MP2 and MP3 FETs MP2 and MP3 become comductive and non-conductive respectively. When the FET MP2 becomes conductive, electric charge of a capacity C1 is discharged, and a capacity C4 is charged, and as the result, the output of the first inverter circuit consisting of FETs MP2 and Mn2 and a resistance R1 approaches 0. Then, an FET Mn3 becomes conductive, and a capacity C3 is discharged, and a capacity C2 is charged, and the output of the second inverter circuit consisting of FETs MP3 and Mn3 and a resistance R2 approaches a voltage -V2. Next, when complementary input signals of 0 and -V1 are applied to gate electrodes of FETs MP2 and MP3, the operation opposite to above is performed. Thus, a buffer circuit - is operated. |
