| Abstract;We propose an Active Body-biasing Controlled (ABC)-Bootstrap PTL (Pass-Transistor Logic) on PD-SOI at 0.5 V-VDD for ultra low power design. Although conventional PTL-based circuits are with difficulty in operation due to lack of driving power as VDD is scaled down, reduction in junction capacitance with SOI (Silicon On Insulator) contributes to higher operation speed for PTL circuits even at low VDD. In our approach, applying active body-biasing to Bootstrap PTL, where capacitive coupling between source and body (CS-body) improves boosting effect of gate voltage, is the key for higher performance without output voltage loss. Moreover, lowering Vth by body-biasing also brings high speed operation. Experimental results show that ABC-Bootstrap PTL has saved 40 % of power consumption when operating at same operation speed as conventional Bootstrap PTL. (author abst.) |
