摘要

本文介绍了一种采用脉宽调节回路的无运放基准电压发生器的设计。采用标准的0.18 μm CMOS工艺设计并仿真了该电压基准电路。布局后仿真结果表明，该电路能够在电源电压低至0.7 V的情况下工作，同时产生202mv的输出电压。实现的温度系数为54 ppm/°C，温度范围从0到100°C。室温下的模拟功耗为400nw。

Design of an op-amp free voltage reference with PWM regulation

This paper presents the design of an op-amp free voltage reference generator which utilizes a pulse width regulated loop. The proposed voltage reference circuit has been designed and simulated in a standard 0.18-μm CMOS technology. Post layout simulation results show that it is capable of operating with supply voltages down to 0.7 V while generating an output voltage of 202 mV. The achieved temperature coefficient is 54 ppm/°C for temperatures ranging from 0 to 100 °C. The simulated power consumption at the room temperature is 400 nW.
