ABSTRACT:
An inverter circuit which is a representative example of the logic circuit includes a p-channel A-MOS transistor and an n-channel transistor. The gain coefficient β of the p-channel A-MOS transistor and n-channel transistor changes according to a voltage on a control gate. The control gate of the p-channel A-MOS transistor and n-channel MOS transistor is connected to an output node of the inverter circuit, and the normal MOS gate is connected to an input node of the inverter circuit. Thus, the ON resistance of the p-channel A-MOS transistor and n-channel transistor is automatically modulated to decrease as the source-drain voltage increases.
