摘要：

<正>A high precision high-order curvature-compensated bandgap reference compatible with the standard CMOS process,which uses a compensation proportional to VTlnT realized by utilizing voltage to current converters and the voltage current characteristics of a base-emitter junction,is presented.Experiment results of the proposed bandgap reference implemented with the CSMC 0.5-μm CMOS process demonstrate that a temperature coefficient of 3.9 ppm/℃is realized at 3.6 V power supply,a power supply rejection ratio of 72 dB is achieved,and the line regulation is better than 0.304 mV/V dissipating a maximum supply current of 42μA.
