Abstract

In this paper, new low-voltage low-TC voltage/current reference is presented. The proposed reference consists of a PTAT current source, a low-voltage bandgap reference, and a current replication circuit. According to evaluation results using a 0.18-μm CMOS process, the proposed reference exhibiting 512-mV output voltage and 0.94-μA output current achieves a minimum supply voltage of 0.7 V. The proposed voltage/current reference achieves temperature coefficients of 54 ppm/°C and 29 ppm/°C with respect to output voltage and current, respectively. This voltage/current reference consumes an overall current of 7.6 μA, and occupies a silicon area of 0.02 mm2.
