摘要： Methods and circuits are provided to create small, power minimizing, multi-channel high voltage drivers for micro-electromechanical systems (MEMS). A resistor calibration circuit is introduced to allow on chip resistor dividers to be calibrated against a single precision high voltage resistor divider, eliminating the cost and printed circuit board real estate associated with multiple resistor dividers connected to each channel. Additionally, a multiple-power rail configuration is provided to reduce power to the overall system by producing several rails generated by a boost converter or a capacitive charge pump, where the voltage output of the rails is produced to group rails of lesser voltage requirement rather than connecting all channels to the same high voltage rail on a dynamic basis.
