CIRCUIT FOR XOR-XNOR LOGIC

摘要

The present invention relates to an XOR-XNOR logic circuit having excellent energy efficiency, and more particularly, a first P-type MOS transistor having one terminal connected to a supply power supply and a first input applied to a gate terminal; A second P-type MOS transistor having one terminal connected to the other terminal of the first P-type MOS transistor and a second input being applied to a gate terminal; A first N-type MOS transistor having one terminal connected to the other terminal of the second P-type MOS transistor, the other terminal connected to the first input, and a gate terminal to which the second input is applied; A second N terminal is connected to a common terminal of the second P-type MOS transistor and the first N-type MOS transistor, the other terminal is connected to the second input, and the first input is applied to the gate terminal. Type most transistor; A first inverter configured to output a first output signal by inverting a potential of a common terminal of the second P-type MOS transistor, the first N-type MOS transistor, and the second N-type MOS transistor applied to an input terminal; And a second inverter configured to generate a second output signal by inverting a first output signal of the first inverter.
