This paper presents an ultra-low-power voltage reference which works on the principle of cancellation of temperature dependency on sub-threshold current. The feedback control which is based on bulk-voltage compensation, not only suppresses the second order temperature dependency but also enables it to achieve a much higher output voltage using supply voltages as low as 0.35 volt. The closed-loop control ensures reliable performance over all process corners in sub-threshold operation. The proposed design achieves a line sensitivity of 0.004 %/V at 20°C and power supply rejection ratio (PSRR) of -45 dB with total power consumption of 12.9 pW. The temperature coefficient is 8.3 ppm/°C over a temperature range of -10-110°C and a supply range of 0.35-2.5V. It is the first complete feedback-controlled pico-watt voltage reference which has such stable temperature coefficient and line sensitivity while having an output voltage (293.5 mV) comparable to the supply voltage even if it is operated with a supply voltage as low as 350 mV. |
