摘要

设计了一种可控高压DC/DC变换器，该变换器在2.8V的供电电压下可产生0 ~ 30V的输出电压。它适用于可调谐滤波器中对MEMS和高压可变电容器件的控制。所提出的DC/DC变换器采用了一种新颖的方法，通过级联两个Dickson电荷泵来降低输出电压(Dickson, 1976)。它的时钟频率为16MHz，采用0.25 μ m Bi-CMOS技术

A Fully Integrated DC/DC Converter for Tunable RF Filters

A controllable high voltage DC/DC converter has been designed that can generate an output voltage from 0 to 30V with a 2.8V supply voltage. It is suitable for controlling MEMS and high voltage varicap devices in tunable filters. The proposed DC/DC converter uses a novel approach to decrease the output voltage by cascading two Dickson charge pumps (Dickson, 1976). It is operating with a clock frequency of 16MHz and is built in a 0.25mum Bi-CMOS technology
