Abstract
we present an ultra low power (200 nA current consumption) reverse bandgap voltage reference operational from supply voltages down to 0.75 V. The reference is a part of microprocessor system on chip implemented in a digital 130 nm CMOS process and has a total area of 0.07 mm 2. The reference accuracy is ±2.5\% (5 sigma) over a temperature range of -20 to 85° C without trimming. With trimming ±0.5\% accuracy is achieved.
