An investing voltage controller and a zero-crossing current switching controller are presented to control the switching timing of the power MOSFETs. Both the controllers use the sample-and-hold circuits and the digital controlled delay lines to tolerate the process variations. The highest operation frequency of the controllers is 6.78 MHz. This chip is fabricated in a 0.18-μm CMOS process. It achieves a peak power conversion efficiency of 67.1% when the input power is 6 mW. ? 2004-2012 IEEE. |
