Classification: CPC H | IPC H

Claim 0:
1. A semiconductor device comprising:
a detection circuit configured to detect a state of a first signal;
an amplification circuit configured to change a gain based on the state of the first signal detected by the detection circuit, the amplification circuit amplifying a first voltage with the gain and outputting a second voltage obtained as a result of amplification, the amplification circuit including an amplification unit, and a feedback resistor switch circuit coupled between an input terminal and an output terminal of the amplification unit, the gain of the amplification circuit being changed by changing a resistance value of the feedback resistor switch circuit based on the state of the first signal; and
a conversion circuit configured to convert the second voltage output from the amplification circuit to first data.
