ABSTRACT:
An IC band-gap voltage reference including a pair of transistors having different emitter areas and driven by an amplifier feedback circuit to produce equal collector currents so as to develop an output voltage corresponding to the band-gap voltage. The amplifier output network includes a resistor network arranged to produce an output voltage which is a predetermined multiple of the band-gap voltage. The circuit provides for independent trimming of elements for adjusting the output voltage magnitude and its temperature coefficient.
