An improved 1.8 V 4.05 ppm/°C curvature corrected bandgap reference circuit
In this paper a curvature corrected bandgap reference circuit is presented which uses folded cascode operation amplifier using beta multiplier as a constant current source. It consists of PTAT current generation circuit and CTAT current generation circuit as two major subparts. The proposed design produces reference voltage of 701.78 mV with temperature coefficient of 4.05 ppm/°C for the temperature range of – 40 to 125 °C.The value of power consumed by the circuit is 86.135 µW at 1.8 V supply voltage. For proposed design the value of power supply rejection ratio is − 60.53 dB for frequency range of 100 Hz to 100 kHz. All simulation results are obtained in cadence virtuoso using SCL 180 nm CMOS technology.
