Abstract

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.

改进型 1.8 V 4.05 ppm/°C 曲率校正带隙基准电路
本文介绍了一种曲率校正带隙基准电路,它使用贝塔乘法器作为恒流源,采用折叠式级联运算放大器。它由 PTAT 电流发生电路和 CTAT 电流发生电路两个主要子部分组成。在 - 40 至 125 °C 的温度范围内,拟议设计产生的基准电压为 701.78 mV,温度系数为 4.05 ppm/°C。在 100 Hz 至 100 kHz 的频率范围内,拟议设计的电源抑制比值为 - 60.53 dB。所有仿真结果均采用 SCL 180 nm CMOS 技术在 cadence virtuoso 中获得。
