Abstract :
A piecewise compensated sub-lV CMOS bandgap reference without using any resistors is presented. The design reduces the silicon chip area with improved circuit robustness. The bandgap reference is simulated with Spectre using SMIC 0.18 mum CMOS technology. It operates at a minimum voltage of 1.5 V and generates a stable voltage at 0.658 V with minimal temperature coefficient of plusmn 5.36 ppm/degC for temperature ranging from -10 to 130degC. It has a line regulation of 0.89% and a high power supply rejection ratio of -42.3 dB. The power consumption of this circuit is as low as 0.229 mA at 1.5 V input voltage.
