ABSTRACT:
A signal receiving device includes: a first conversion unit comprising a first input terminal to which a signal including a voltage signal and a reference voltage is inputted, and a first output terminal which output a first current signal voltage-current converted from the signal; a second conversion unit comprising a second input terminal to which the reference voltage is inputted, and a second output terminal which output a second current signal voltage-current converted from the reference voltage; a current mirror circuit comprising a third input terminal to which the second current signal is inputted, and a third output terminal which output a third current signal corresponding to the second current signal; and an output unit connected to both the first and third output terminals.
