This paper describes a bandgap voltage reference circuit that operates with a 3 V power supply and is compatible with a digital CMOS process. The use of a simple circuit topology results in a small silicon area of 0.07 mm2, a power consumption of 1 mW and a high power supply rejection over a wide frequency band. The circuit realizes a temperature coefficient of 85 ppm/°C and a standard deviation of 20 mV without trimming
