Abstract(in Japanese) (See Japanese page)
Abstract(in English) By using new substrate-bias power lines [V_
'(>V_
), V_'()]in addistion to common power supply lines [V_
,V_],CMOS circuits could be modeled to have four kinds of threshold voltages by the four separated substrate-biases. We proposed a circuit scheme making the most of pull-up / pull-down MOSFETs with high V_T, which are biased by [V_
', V_'].The source terminals of these transistors were only connected to the base of [V_
, V_][1].In this paper, we optimize the domono CMOS circuits based on 0.35μm design-rule by doing T-SPICE simulation with BSIM3v3 model. It is shown that the 4-parallel 3-input NAND combinational logic circuit with the driver inverter can reduce the delay time to 67%, and the area to 69%compared to the equivalent static CMOS logic circuit.
