Abstract
Methods, devices, modules, and systems for a band-gap reference voltage detection circuit are provided. One embodiment for a band-gap reference voltage detection circuit includes a Brokaw cell having a band-gap reference voltage, and a circuit portion for indicating the magnitude of an input voltage signal with respect to the band-gap reference voltage. The input voltage is applied to transistor bases of the Brokaw cell.
