Title: Cmos circuit
Inventor: OKUMURA KOICHIRO
IPC: H03K19/003
Filed: 1986-05-23
Abstract: PURPOSE:To stop or considerably reduce the variation of a threshold voltage and attain a stable operation even for a low supply voltage by forming a CMOS circuit with the first and second circuits consisting of P-channel and Nchannel enhancement MOSFETs respectively and an N-channel depletion MOSFET and using the first terminal as the output terminal. CONSTITUTION:A maximum value of the potential in a terminal 102 is fixed to ¦VTD¦ when the voltage of a power source Vcc is higher than ¦VTD¦, and this maximum value is equal to V when the voltage of the power source Vcc is lower than ¦VTD¦. Therefore, the voltage between the source and the drain of the N-channel MOSFET constituting an N-channel circuit 2 is held down to a value lower than an allowable maximum voltage independently of the level of the voltage of the power source Vcc. The increase of the supply current due to reduction of the withstanding voltage between the drain and the source and the variation of the threshold voltage due to hot electron injection are prevented or considerably reduced. The conduction resistance of a MOSFET D13 is not changed very much even for a low supply voltage because the gate voltage of the N-channel MOSFET D13 is fixed to the earth voltage, and the operation is stabilized.
