Abstract
A low supply headroom bandgap voltage reference generation circuit for generating a bandgap reference voltage from a supply voltage can include a first delta base-to-emitter voltage generation circuit, which can include a first Darlington configuration of a first pair of transistors arranged in a differential pair with a second Darlington configuration of a second pair of transistors. A first input to the first Darlington pair of transistors can be connected to an output voltage node of the bandgap voltage reference generation circuit and a second input to the second Darlington pair of transistors can be connected to the output voltage node of the bandgap voltage reference generation circuit via a first delta base-to-emitter-voltage resistor.
