A Near-1V 10ppm/℃ CMOS Bandgap Reference with Curvature Compensation
-
Abstract
A low voltage bandgap reference with curvature compensation is presented.Using current mode structure,the proposed bandgap circuit has a minimum voltage of 900mV.Compensated through the VEB linearization technique,this bandgap reference can reach a temperature coefficient of 10ppm/℃ from 0 to 150℃.With a 1.1V supply voltage,the supply current is 43μA and the PSRR is 55dB at DC frequency.This bandgap reference has been verified in a UMC 0.18μm mixed mode CMOS technology and occupies 0.186mm2 of chip area.-
