Abstract: A novel CMOS bandgap reference is presented.The output reference of this new current mode structure can be set to an arbitrary value above the bandgap voltage of silicon,avoiding offset in application.It also overcomes the systematic mismatch of conventional current mode bandgap references.The proposed bandgap reference has been implemented in UMC 0.18μm mixed mode technology.Under the supply voltage of 1.6V,the proposed bandgap reference provides an output reference of 1.45V and consumes 27μA of supply current.Using no curvature compensation,it can reach a temperature coefficient of 23ppm/℃ from 30 to 150℃ with a line regulation of 2.1mV/V from 1.6 to 3V and a PSRR of 40dB at DC frequency.The chip area of the bandgap reference (without pad) is 0.088mm2.
