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 outp...

Zusammenfassung: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
