Abstract :
An Adaptive Voltage Scaling DC-DC Converter with Embedded Minimum Energy Point Tracking technique is presented in this paper. Three techniques, named Minimum Energy Point (MEP) Tracking (MEPT), Adaptive Voltage Scaling (AVS) and Pulse Skip Modulation (PSM), are combined in the proposed converter. The circuit is simulated in a 0.13μm standard CMOS technology, the simulation result shows that, the output voltage of the converter varies from 0.2V~1.5V. When the frequency ranges from 25kHz to 125MHz, furthermore, the circuit can successfully tracks the MEP at 575mV@20MHz and the MEP at 0.5V@10MHz.
