| Zusammenfassung: | The utility model provides a current source circuit and a semi-physical simulation system. The current source circuit comprises a power amplification assembly, an instrument amplification assembly and a first adjusting resistor used for adjusting the gain of the instrument amplification assembly; an input terminal of the power amplification assembly receives a voltage signal, and an output terminal of the power amplification assembly outputs an amplified current signal; an input terminal of the instrument amplification assembly is connected with the output terminal of the power amplification assembly, and an output terminal of the instrument amplification assembly is connected with the input terminal of the power amplification assembly; and the first adjusting resistor is connected with input terminals of the instrument amplification assembly. According to the current source circuit and the semi-physical simulation system, the problem that the gain adjusting range of a traditional current source current is re |
