Abstract
The technique of using time-based proportional integral (PI) control for high-frequency buck converter design is presented in this research. By using time as the primary processing variable, it provides exceptional resolution and speed without requiring error amplifiers, bulky capacitors, and high-resolution A/D converters. The proposed PI controller for a buck converter is made using a 65nm CMOS process, takes up 0.001 mm2 and can operate over a switching frequency 4.5 MHz. This controller can generate a tailored Pulse Width Modulation (PWM) signal to meet the precise duty cycle requirements of a buck converter, thus enabling the desired output voltage to be achieved, with a steady-state output ripple voltage of 0.7 mV.
