Abstract
A voltage sensing circuit is disclosed, which utilizes a reference voltage generating circuit for producing a reference voltage whose value is determined as a function of absolute temperature, independent of circuit element variations, the reference voltage being generated by means of a pair of MOS field effect transistors having different values of Id/K, where Id is drain current and K is the channel pattern ratio W/L.
