| Zusammenfassung: | Disclosed is an integrated circuit for a near-field radio, including an oscillator configured to output a carrier frequency, an inductor capacitor (LC) tank antenna circuit configured to resonate at a resonance frequency, a frequency measuring circuit configured to measure the resonance frequency of the LC tank antenna circuit and compare the resonance frequency to the carrier frequency, and a controller to adjust the frequency of the LC tank antenna circuit to the carrier frequency. |
