Abstract

A precise curvature compensated CMOS bandgap voltage reference is presented, which utilizes temperature-independent current and an improved voltage-transfer unit to compensate for the higher order of the V_BE. The new proposed bandgap voltage reference is implemented in 0.13 mum CMOS technology and operates with 0.9V supply voltage consuming 48muW at room temperature. The circuit achieves 5ppm/degC of temperature coefficient with temperature range from -40 to 85degC. With 0.9V supply voltage, the power noise rejection ratio is -25 dB at 10 kHz
