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 VBE. 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
