Abstract
A new CMOS curvature compensated bandgap reference circuit which uses two different types of material to realize its resistors in an improved structure is presented. Implemented in a 0.18 μm technology, it achieves performance of a temperature coefficient of 1.8 ppm/°C over 0 ~ 100°C, a line regulation of 0.017%/V over the range 1.2 ~3 V and a power supply rejection ratio of 82 dB@1 Hz. It can offer a reference voltage of 1.1 V but occupy an area of only 0.049 mm2.
