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 V/sub thn/ /spl ap/ |V/sub thp/| /spl ap/ 0.9 V at 0/spl deg/C, the minimum supply voltage of the proposed voltage reference is 0.98 V, and the maximum supply current is 18 /spl mu/A. A temperature coefficient of 15 ppm//spl deg/C from 0/spl deg/C to 100/spl deg/C is recorded after trimming. The active area of the circuit is about 0.24 mm/sup 2/.
