Abstract:
1. A semiconductor device comprising: an antenna circuit; a first resistor; a second resistor; a transistor; a capacitor; a logic circuit; a first constant-voltage power supply line; and a second constant-voltage power supply line, wherein one terminal of the first resistor is electrically connected to one of a source and a drain of the transistor, wherein the other terminal of the first resistor is electrically connected to the antenna circuit, wherein a gate of the transistor is electrically connected to one terminal of the capacitor and one terminal of the second resistor, wherein the other one of the source and the drain of the transistor is electrically connected to the first constant-voltage power supply line, wherein the other terminal of the second resistor is electrically connected to the logic circuit, wherein the other terminal of the capacitor is electrically connected to the second constant-voltage power supply line, and wherein impedance of the capacitor is at least lower than combined impedance of the second resistor and the logic circuit.
