【 摘 要 】

References(6)Cited-By(1)A novel high precision high order curvature-compensated bandgap reference (BGR) is presented in this paper designed using the subthreshold current of self-cascode transistors in standard digital 0.18µm CMOS process. Simultaneously its temperature coefficient is typically 4.6ppm/°C in the temperature range of -25 to 120°C with a supply current of 17.25µA. A power supply rejection ratio (PSRR) of -51dB is achieved while the layout area is no more than 0.0022mm2.
