초록

This paper presents a high efficient two-stage interleaved synchronous buck CMOS DC-DC converter. The proposed circuit has a fixed duty cycle as 0.5 by an added buck converter. And it causes the best ripple cancelation of the output current ripple. The proposed circuit was simulated by HSPICE with a standard CMOS $0.35{\mu}m$ process parameter.
