The present invention is an emittance conversion circuit having a first terminal and a second terminal, wherein the emittance conversion circuit is provided with a conversion subject circuit, which amplifies or attenuates at desired frequency/gain characteristics and outputs the result, a difference signal detection circuit, which supplies to the input terminal of the conversion subject circuit a signal of the difference between the signals arising at the first and second terminals, an emittance conversion drive circuit, which performs differential output processing generating a voltage of the difference between a correction voltage and the signal output from the conversion subject circuit and outputs a feedback signal to the emittance conversion circuit, and an emittance conversion generation circuit, which has an emittance conversion generation effect that generates an emittance such that a signal of the sum or difference of the currents or voltages of the signal input to the first and second terminals and the input feedback signal arises at the first and second terminals, a signal of the difference of the signals arising at the first and second terminals being input to the emittance conversion drive circuit as the correction voltage. |
