Abstract
This paper proposes a single on/off reference tracking buck converter for DVFS application with a novel turning point prediction based on the turning point of the output voltage. The equation to determine the turning point of the output voltage for optimal reference tracking is analyzed and implemented by a current multiplier and divider circuit. In addition, a new reference tracking scheme is introduced to avoid undershoot of output voltage caused by load change. This work is simulated in a 0.13-μm CMOS process and simulation results show fast reference tracking capability with 1.48 μs/V for up reference tracking, 1.91 μs/V for down reference tracking, and effective reduction of the undershoot and overshoot problem.
