ABSTRACT:
An electronic system such as an electronic timepiece includes multi-level, integrated injection circuitry and a multiplexed liquid crystal display. A low-power voltage regulator is provided for driving the liquid crystal display and a current regulator is provided for driving the integrated injection logic circuitry. The current regulator is stacked between the logic levels in order to provide a fractional regulated voltage for driving the liquid crystal display without additional circuit elements and associated current drain.
