Abstract
A buck converter with maximum charging current control in achieving high tracking speed is presented. An adaptive delay compensation scheme is employed to keep the switching frequency at 850 kHz within plusmn2.5% across the whole operation range. The integrated buck converter was fabricated using a 0.35 mum CMOS process and all functions are verified by extensive measurements.
