In this paper, we propose an Active Body-biasing Controlled (ABC)-Bootstrap PTL (Pass-Transistor Logic) on PD-SOI for ultra low power design. Although simply lowering the supply voltage (VDD) causes a lack of driving power, our boosted voltage scheme employing a strong capacitive coupling with ABC-SOI improves a driving power and allows lower voltage operation. We also present an SOI-SRAM design boosting the word line (WL) voltage higher than VDD in short transition time without dual power supply rails. Simulation results have shown improvement in both the delay time and power consumption.
