摘要
A voltage reference circuit for providing a predetermined reference voltage at an output terminal which is independent of variation in supply voltage. The voltage reference circuit includes first and second semiconductor elements coupled between supply voltage terminals of a power supply, with the first and second semiconductor elements being connected in series with first and second impedances. The reference voltage is provided at the common terminal of the first and second impedances. The temperature coefficient of voltages produced by the first and second semiconductor elements in combination with the first and second impedances provide a reference voltage with a predetermined temperature coefficient. A tuning circuit is also included to permit fine adjustment of voltage level changes due to process variations.
