Title: Buck Converter for Low Power Applications
Keywords: buck converter, CMOS process, low power applications, high switching frequency

Abstract: Buck converter for low power applications is designed and investigated on standard 0.35-μm CMOS process. The blocks of the system, including bandgap reference, ramp generator, error amplifier, comparator, buffer and power buck stage, are optimized using CADENCE design tools. The energy losses in the controlling stages are minimized in order to improve the overall converter efficiency. A relatively high switching frequency of about 147 MHz is used in order to decrease the size of the filtering components. Power efficiency of about 70% is achieved for voltage conversion from 3.6V down to 1.2V. The converter systems shows stable performance over temperature, input voltage, and output load variations.
