Abstract :
This paper described a digitally controlled Buck converter. In this converter, the compensator implements the classic linear PID control law by the fixed-point algorithm. A proposed verification method is performed in Simulink environment. The structure of low area and power cost Ring ADC and high resolution DPWM is also introduced, respectively. The consistent mathematic and Spice simulation result demonstrate the design validity of the whole system.
