We have developed a latch-up free Switched Capacitor (SC) type voltage up converter on 0.35 /spl mu/m FD-SOI technology. In this paper, we propose approximate theoretic expressions of the power efficiency and the output voltage. A test chip confirms the validity of these theoretic expressions. As a result, we can optimize the performances for various load currents of the up converter. The up converter achieved a power conversion efficiency of 93.5% including self-power. consumption at 1 mA DC load current, where switching frequency is 100 kHz, input voltage is 0.8 V, V out is 1.55 V, and capacitance is 10 /spl mu/F.
