Abstract :
A charge recycling sense amplifier based logic is presented.. This logic is derived from the sense amplifier based logic, which is a logic style with signal independent power consumption. It has been proven previously to protect security devices such as smart cards against power attacks. Experimental results show that the use of advanced circuit techniques, which enable charge recycling and intermediate precharge voltages, saves 20% in power consumption and 63% in peak supply current and that the logic style preserves the energy masking behavior of the sense amplifier based logic.
