摘要：Disclod is an integrated circuit for a near-field radio, including an inductive-capacitive (LC) tank antenna circuit designed to operate at a predetermined carrier
frequency, the tank LC tank antenna circuit including a variable capacitor and an antenna白带异常的表现
element, a transmitter configured to output a channel sounding signal (CSS) to the LC tank antenna circuit, a receiver to receive the CSS and a tank respon from the LC tank antenna circuit, a tank respon estimator to extract the tank respon of the LC tank antenna circuit by removing the CSS from the received signal and determining an oscillation frequency of the LC tank antenna circuit, and a controller to adjust a reactance of the LC tank antenna circuit to resonate the LC tank antenna circuit and change the oscillation frequency to the predetermined carrier frequency.
