摘要
单片开关降压转换器采用标准的0.35 μ m CMOS工艺设计。不同的控制技术，如脉宽调制(PWM)和脉频调制(PFM)进行了研究。实测结果表明，与标准恒频PWM控制相比，PFM控制在轻负载下具有更高的效率。在开关频率为150 MHz时，电压从3.6 V转换到1.2 V, PWM控制的效率约为76%。
Monolithic buck converter for CMOS process technologies
Monolithic switching buck (step-down) converter is designed on standard 0.35-mum CMOS process. Different control techniques such as Pulse-Width Modulations (PWM) and Pulse-Frequency Modulations (PFM) are investigated. The received results show that PFM control indicates higher efficiency at light-loads compare to standard constant frequency PWM control. Efficiency of about 76% is achieved for the PWM control at switching frequency of 150 MHz for voltage conversion from 3.6 down to 1.2 V.
