A High-Precision Compensated CMOS Bandgap Voltage Reference Without Resistors

A high-precision compensated CMOS bandgap reference without resistors, which is fabricated in 0.5- μm CMOS technology, is presented in this brief. The circuit uses ratioed transistors together with the inverse-function technique to produce a first-order temperature-insensitive voltage reference. More importantly, a higher-order curvature correction method called VBE linearization is presented to directly compensate for the thermal nonlinearity of the base-emitter voltage. The power consumption of the proposed reference is 0.648 mW at 3.6 V. A temperature coefficient of 11.8 ppm/°C and power supply rejection ratio (PSRR) of more than 31 dB at low frequencies are easily achieved.
