Band-gap reference voltage generator for low-voltage operation and high precision
摘要：
Provided is a band-gap reference voltage generator for low-voltage operation and high precision. The band-gap reference voltage generator minimizes voltage drop by connecting resistors in parallel to bipolar transistors, and cancels temperature dependence by properly adjusting a resistor of an output stage, so that it can provide a stable reference voltage that is unaffected by a change in temperature in spite of a low power supply voltage. Further, the band-gap reference voltage generator minimizes variation of the reference voltage caused by offset noise by switching of input and output voltages at input and output stages of a feedback amplifier, so that it can provide a precise reference voltage.

提供一种用于低电压操作和高精度的带隙参考电压发生器。 带隙参考电压发生器通过将电阻并联连接到双极晶体管来最小化电压降，并通过适当调整输出级的电阻来消除温度依赖性，从而可以提供不受温度变化影响的稳定参考电压 尽管电源电压低。 此外，带隙参考电压发生器通过切换反馈放大器的输入和输出级的输入和输出电压来最小化由偏移噪声引起的参考电压的变化，使得其可以提供精确的参考电压。
