A 300-μW BLE-Compliant Packet-Based Data-Agnostic Clock-Harvesting RX Achieving −85/−70 dBm Sensitivity for ±40/±15 ppm Accuracy https://sscs.ieee.org/wp-content/themes/movedo/images/empty/thumbnail.jpg 150 150 https://secure.gravatar.com/avatar/8fcdccb598784519a6037b6f80b02dee03caa773fc8d223c13bfce179d70f915?s=96&d=mm&r=g
Abstract:
An ultralow-power Bluetooth low energy (BLE)-compliant crystal-less clock-harvesting receiver is presented that uses the BLE advertising packets (APs) to calibrate an on-chip frequency reference with ±400 ppm initial frequency offset. The proposed front-end, fabricated in 22 nm FDSOI, is capable of pushing the frequency accuracy of the reference further to below ±40/±15 …
