Abstract
A majority circuit comprises CMOS circuits is adapted to prevent operation errors due to disagreement of conductance among the transistors of the circuits. Such a majority circuit can realize a large fan in. More specifically, the majority circuit comprises a plurality of CMOS circuits connected in series and having respective gates operating as input sections for receiving a plurality of binary signals, a binary signal detecting section having a current control transistor of the first gate conduction type connected in series to the transistor of the first conduction type and a current control transistor of the second gate conduction type connected in series to the transistor of the second conduction type in each of the CMOS circuits, an output inverter circuit for producing a binary output as output of majority decision for the binary input signals according to the change in the potential of the node of the binary signal detecting section and a bias circuit for controlling the gates of the current control MOS transistors.
