ABSTRACT:
A reference circuit generates a reference voltage from a supply voltage. The reference circuit includes a current generating unit for generating generated currents. An output unit of the reference circuit generates the reference voltage based on the generated currents. A startup unit of the reference circuit allows the reference voltage to switch between different voltages levels in different modes.
