Patent abstract
The current-voltage converting circuit converts an input current signal into a voltage signal, and the single-differential converting circuit converts the voltage signal into differential signals so as to output the differential signals. The first and second low-pass filters input outputs from the single-differential converting circuit, respectively, and the voltage-current converting circuit converts a difference between the output voltages from the first and second low-pass filters into a current signal. The current-voltage converting circuit inputs a voltage held in the hold capacitor as a control signal and converts the input current signal into a voltage signal using a current-voltage converting gain according to the control signal.
