Reference voltage circuit

The invention relates to a reference voltage circuit. The reference voltage circuit comprises a reference current circuit, a voltage compensation circuit and a reference voltage output circuit, the first end of the reference current circuit and the first end of the reference voltage output circuit are both connected with a voltage source, and the second end of the reference current circuit and the second end of the reference voltage output circuit are both connected with the voltage compensation circuit; the voltage compensation circuit is used for compensating the voltage of the second end of the reference voltage output circuit, so that the error between the voltage of the second end of the reference voltage output circuit and the voltage of the second end of the reference current circuit is smaller than a preset voltage threshold value. The reference voltage circuit is simple in structure, high in PSR capacity and simple in implementation process. 本申请涉及一种基准电压电路，该基准电压电路包括基准电流电路、电压补偿电路和基准电压输出电路；基准电流电路的第一端和基准
