ELECTRONIC CIRCUIT FOR CONFIGURING AMPLIFYING CIRCUIT CONFIGURED TO OUTPUT VOLTAGE INCLUDING LOW NOISE

The invention provides an electronic circuit (200_1) which includes a first current generating circuit (240_1) configured to output a first operating current based on a first operating voltage (VDD1);and an input circuit (210_1, 220_1) configured to: receive a first current corresponding to a first input voltage and a second current corresponding to a second input voltage, wherein the first current and the second current are based on the first operating current; receive a third current and a fourth current that are generated based on the first operating voltage (VDD1); and generate a fifth current corresponding to the second input voltage based on a second operating current. The electronic circuit (200_1) is configured to generate an output voltage associated with a difference between thefirst input voltage and the second input voltage based on the second current, the fourth current and the fifth current, and the fourth current corresponds to the third current. 提供了一种电子电路。电子电路包括：第一电流生成电路，被配置为基于第一操作电压来输出第一操作电流；
