ABSTRACT:
An electronic system, such as an electronic timepiece, utilizes multi-level, integrated injection logic circuitry and a liquid crystal display. A low-power voltage regulator is provided for driving the liquid crystal display which has a negative temperature coefficient. The voltage regulator provides a negative temperature coefficient which tracks the negative temperature coefficient of the liquid crystal display by utilizing the multi-levels of the integrated injection logic circuit to provide the electrical equivalent of a plurality of series-connected diodes without additional current drain.
