Signed digit CMOS (SD-CMOS) logic circuits with static operation

A design is proposed for a voltage-mode signed digit CMOS (SD-CMOS) logic circuit. This circuit can provide stable, static operation with a multi-voltage power supply, and it can be fabricated by applying standard CMOS process technology. Key components based on the proposed circuit design, such as a driver circuit, an inverter circuit, a general CMOS logic circuit, and a D-F/F are described. Each circuit element number, operation speed, and power consumption are examined from the viewpoint of system applications.
