提出了一种能够自产生基准电压和偏置电流，并且锁定阈值电压和迟滞量稳定的新型欠压锁定电路。

A novel under-voltage lockout circuit is proposed which could generate reference voltage and bias current itself, and could stabilize lockout threshold voltage and hysteresis quality.

基准源模块广泛的应用于模拟和混合电路中，如A/D、D/A转换器，电压调谐器，电压表，电流表等测试仪器以及偏置电路。

Reference sources are widely used in analog and mix-mode circuits, such as A/D, D/A converters, voltage regulators, measurements, instrumentation circuits, and bias circuits.

基准源作为其中关键模块之一，不仅需要为系统提供精准的偏置电压和偏置电流，差分基准源还将为其提供比较电平和残差电压，它的性能将直接影响到系统指标。

Reference is the key part of ADC, not only providing the bias voltage and current for the system but also playing the part of the compared voltage and subtracted voltage.
