3-valued logic inverter circuit

摘要

PPROBLEM TO BE SOLVED: To provide a three-valued logic inverter circuit which can be constituted of a small number of MOS and can obtain excellent characteristics. PSOLUTION: The substrate terminals of MOSep1, gp2, bp3 are connected with a first substrate voltage, the substrate terminals of MOS of MOSbn1, bn2, gn3 are connected with a second substrate voltage, the source side of MOSep1, bp3 is connected with a first signal voltage, and the source side of MOSbn1, bn2 is connected with a second signal voltage. Furthermore, the source side of MOSgn3 is connected with a third signal voltage, the source side of the MOSgp2 is connected to the drain side of the MOSbp3, and the drain side of the MOSgp2 or MOSbn2 serves as the output node.
