Patent ID: 7751793

Claim:
A method, comprising: receiving a first signal modulated on a first carrier frequency; demodulating the first signal using a circuit that includes first and second inductors formed on a semiconductor substrate, the first and second inductors including first and second conductive tracks, each track having first and second terminals connected to the respective conductive tracks at first and second ends thereof; receiving a second signal modulated on a second carrier frequency; and demodulating the second signal using a circuit that includes third and fourth inductors formed on a semiconductor substrate, where the third inductor is a portion of the first inductor, defined by a segment of the first conductive track between the second terminal of the first conductive track and a third terminal of the first conductive track, connected to an intermediate point of the first conductive track, and the fourth inductor is a portion of the second inductor, defined by a segment of the second conductive track between the second terminal of the second conductive track and a third terminal of the second conductive track, connected to an intermediate point of the second conductive track.
