The crystal-free wireless device also includes a relaxation ring oscillator configured to communicate with the frequency calibration module. The relaxation ring oscillator is further configured to receive a calibration signal or periodic radio frequency packets from a wireless network and provide a reference signal to the frequency calibration module. The relaxation ring oscillator is a crystal-free oscillator. The frequency calibration module is configured to generate a calibration signal that is fed back through a Frequency Locked Loop (FLL) to the local RF oscillator to calibrate the local RF oscillator. The calibrated local RF oscillator is configured to generate a clock signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Crystal-free wireless devices","description":"A crystal-free wireless device includes a frequency calibration module and a local radio frequency (RF) oscillator having a first frequency and configured to communicate with the frequency calibration","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11522566","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
