Patent ID: 8328105

Claim:
A semiconductor device comprising: an antenna; a first transistor, wherein a drain and a gate of the first transistor is electrically connected to one end of the antenna; a first resistor, wherein one end of the first resistor is electrically connected to a source of the first transistor; a second transistor, wherein one of a source and a drain of the second transistor is electrically connected to the one end of the first resistor, and a gate of the second transistor is electrically connected the other end of the first resistor; a second resistor, wherein one end of the second resistor is electrically connected to the other of the source and the drain of the second transistor; one or a plurality of third transistors, wherein a drain and a gate of any one of the one or the plurality of third transistors is electrically connected to the other end of the first resistor; a fourth transistor, wherein a gate of the fourth transistor is electrically connected to the one end of the second resistor and the other of the source and the drain of the second transistor; and a fifth transistor, wherein a gate of the fifth transistor is electrically connected to the gate of the fourth transistor, and one of a source and a drain of the fifth transistor is electrically connected to the drain and the gate of the first transistor, wherein the other end of the antenna, a source of the one or the plurality of third transistors, the other end of the second resistor, the other of the source and the drain of the fourth transistor, and the other of the source and the drain of the fifth transistor are grounded.
