IEEE(1995)A Low Supply Voltage High PSRR Voltage Reference in CMOS Process
by Khong-Meng Tham and Krishnaswamy Nagaraj
Abstract—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 mWand 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. |
