Buck Converter with Variable Output Voltage for Dynamic Voltage Scaling (DVS) Applications

In this research, a novel buck converter capable of dynamically adjusting the output voltage with remarkable scheme to meet the demands of dynamic voltage scaling (DVS) applications is presented. The converter employs a four-bit resistor network switch, enabling the output voltage to be varied based on the workload requirements during runtime. To demonstrate the feasibility of our approach, the proposed chip was implemented using a 0.1Sum lp6m CMOS process. Experimental measurements revealed that the four-bit resistor switch effectively alters the output voltage within the range of 1. 0V to 2. 4V, with increment of 0. 1V achievable by adjusting the switch settings from 0001 to 1111. This buck converter is intended to serve as switching output voltage for power electronic systems.
