An Area-Efficient Temperature Compensated Sub-Threshold CMOS Voltage Reference

This paper presents an area-efficient voltage reference that mitigates the shortcomings of technology scaling. The proposed voltage reference offers temperature coefficient of 34 ppm/°C, line sensitivity of 2.88 %/V, with peak-to-peak process variation of 43 m V. The voltage reference operates in supply range from 0.7 V to 1.1 V. By exploiting the minimum possible gate length, it can be implemented in compact area of $0.00016\ \mathrm{mm}^{2}$ ,
