Abstract:This paper presents a recursive stacking body-bias NAND for extremely low voltage application. Our proposed NAND utilizes recursive-stacking and body-bias techniques to achieve extremely low-voltage operation. The former suppresses off-leakage current of MOSFETs and enhances the voltage gain of the NAND gate. The latter achieves on-current enhancement and the voltage gain improvement of the NAND gate. Performance improvements of our proposed NAND gate are theoretically analyzed and discussed. Simulation of our… Show more
