A sub-1V CMOS voltage reference generator

In this paper, a low-voltage (sub-1 Volt) resistor-free voltage reference is presented. The complete design was simulated and laid out in AMI 0.5 μm CMOS process. The design provides a temperature coefficient of 12.8 ppm/ C over a temperature range from 25 to 100 °C and occupies an area of 0.037 mm . Circuit description and experimental results of the proposed design are also presented.
