Abstract

A new sub-1-V CMOS bandgap voltage reference without using low threshold voltage device is presented in this paper. The new proposed sub-1-V bandgap reference with startup circuit has been successfully verified in a standard 0.25 μm CMOS process. The experimental results show that, at the minimum supply voltage of 0.85 V, the output reference voltage is 238.2 mV with an effective temperature coefficient of 58.1 ppm/°C while DC current is 28 μA. At 0.85 V supply voltage, the measured power noise rejection ratio is -33.2 dB at 10 kHz.
