带隙基准电压源(Bandgap)设计范例
The performance of a bandgap reference circuit is improved by increasing the ΔVBE, and thereby correspondingly decreasing the input sensitivity of the error amplifier in the control loop. The ΔVBE can be increased by presenting stacked diode configurations at the amplifier inputs, by increasing ...
