| Abstract: | A sub-1-V CMOS bandgap voltage reference requiring no low threshold voltage device is introduced in this paper. In a CMOS technology with Vthn ≈ |Vthp| ≈ 0.9 V at 0°C, the minimum supply voltage of the proposed voltage reference is 0.98 V, and the maximum supply current is 18 μA. A temperature coefficient of 15 ppm/°C from 0°C to 100°C is recorded after trimming. The active area of the circuit is about 0.24 mm2 |
