Abstract
An LC oscillator is provided. The LC oscillator includes a single layer inductor disposed within a single layer inlay, wherein the single layer inductor is configured in a spiral pattern within the layer of the inlay, wherein an integrated circuit is mounted on the single layer inlay; and a capacitor included in the integrated circuit, wherein the capacitor is connected to the single layer inductor.
Claims19
An inductor-capacitor (LC) oscillator, comprising:
- a single layer inductor disposed within a single layer inlay, wherein the single layer inductor is configured in a spiral pattern within the layer of the inlay, wherein an integrated circuit is mounted on the single layer inlay;
- and
- a capacitor included in the integrated circuit, wherein the capacitor is connected to the single layer inductor.
An oscillator calibration circuit, comprising:
- a signal frequency detector for producing a reference signal based on a received over-the-air signal, wherein the signal frequency detector is configured to detect a frequency of the over-the-air signal;
- an inductor-capacitor (LC) oscillator;
- and
- a first frequency locking circuit (FLC) coupled to the signal frequency detector and to the LC oscillator, wherein the first FLC calibrates the frequency of the LC oscillator using the reference signal of a radio frequency (RF) carrier frequency, wherein the reference signal is utilized for calibrating the LC oscillator based on the frequency of the detected over-the-air signal.
