Abstract
In one form, a reference circuit includes a measurement circuit and a determination circuit. The measurement circuit has an output for providing a ratio of a difference in base-to-emitter voltage (V) of a bipolar device at different current densities to a Vof the bipolar device at a first current density. The determination circuit has an input coupled to the measurement circuit, and an output for providing a digital value of a parameter in response to the ratio. In another form, the reference circuit further includes a voltage generation circuit having an input coupled to the determination circuit, and an output, for modulating an analog voltage using the digital value to provide a reference voltage to the output, wherein the reference voltage is temperature compensated over a temperature range.
