In the ideal case, R3 is 0, so I1 is I2, so the output voltage UO is-I2 is R3, but in practice R3 is not zero, so the larger Rs is than R3, the higher the conversion accuracy is, and in a particular conversion process, the larger Rs can be set. Fig. 3 is a relatively mature current-voltage conversion circuit in the prior art, and the detailed calculation process is not described herein.
