Patent ID: 7098701

Claim:
A receiving apparatus, including: an input unit which inputs a first input signal and a second input signal, respectively; an output signal generator which generates a first output signal from a current signal of the first input signal and which generates a second output signal from a current signal of the second input signal; a first control signal generator which generates a first control signal where a reference voltage is dropped by a potential difference which is generated by delivering the current signal of the first input signal; a second control signal generator which generates a second control signal where the reference voltage is dropped by a potential difference which is generated by delivering the current signal of the second input signal; a first voltage adjusting unit which adjusts, by the second control signal, a magnitude of a voltage signal of the first input signal in said input unit according to a magnitude of the current signal of the first input signal; a second voltage adjusting unit which adjusts, by the first control signal, a magnitude of a voltage signal of the second input signal in said input unit according to a magnitude of the current signal of the second input signal; and an output unit which outputs a voltage signal according to a difference between the first output signal and the second output signal.
