摘要：
A 0.6mum CMOS integrated digital PID controller for a buck converter is fabricated and tested. It consists of (1) a VCO driving a counter to serve as an ADC; (2) a PID compensator that employs a programmable integration time for enhancing accuracy and stability; and (3) a dual-band switching PWM generator with a modified tapped delay line for better output resolution and area efficiency. The converter switches at 1MHz, while the tracking time is 50 mus for a step change of 1V.
