A Capacitor Charge Pump DC-DC Converter for Physics Instrumentation
We have prototyped a switched capacitor DC-DC converter aimed at powering low voltage integrated circuits in particle physics instrumentation. The ideal output current is 4 times the input current. The prototype was built using a CMOS integrated circuit containing all switches and switch driver circuitry, with external capacitors and clocks. We present measurements of performance with and without irradiation.
