摘要：

A precision curvature-compensated bandgap reference (BGR) is proposed and implemented using a standard 0.18-mu m CMOS process. With a new and precise circuit configuration, the thermal nonlinearity of emitter-base voltages can be fully compensated, achieving an ultra-low temperature coefficient (TC) of 0.58 ppm/degrees C from -40 degrees C to 110 degrees C. The minimum required supply voltage is 1.2V and the current consumption at 27 degrees C is 48 mu A. At 27 degrees C, the line regulation performance is 0.015%/V with a supply voltage range of 1.2V to 1.8V.
