Abstract
A band-gap voltage reference circuit which incorporates a band-gap differential amplifier supplied with constant, temperature-independent current, a high gain differential-to-single-ended converter, temperature-compensated negative feedback means and a common source of biasing to serve as a device to provide an output reference voltage so that the output reference voltage is precise and independent of variations in temperature, loading and power supply voltage. An improved amplifier is also disclosed.
