Abstract
A low power bandgap circuit device that generates temperature independent reference voltages and/or zero temperature coefficient currents is disclosed. The circuit comprises a first pair of transistors, an amplifier, a star connected resistive network, and a second pair of transistors, wherein zero temperature coefficient currents are generated through mirroring and reuse of current from the star connected resistive network.
