Abstract:
This paper was focused over the efficiency evaluation and optimization of switchmode dc-dc converter for RF applications. AMS CMOS 0.35 µm technology was used for investigations. Effect of different factors over the circuit’s behavior was considerate. Soft-switching control techniques was analyzed and compared with basic regulation’s method of buck converter. Influence of currentmode of operation was explored. Efficiency of about 76 % at 400 MHz switching frequency is illustrated for voltage conversion from 3.6 V to 1.2 V.
