The Bluetooth signal receiving device includes an energy detector circuit, a radio frequency (RF) power detector circuit, an analog-digital converter circuit, and an automatic gain control circuit. The energy detector circuit detects a significant signal, having energy higher than background noise by a threshold value or more, from a received signal. The RF power detector circuit detects the magnitude of the received signal. The analog-digital converter circuit converts the analog value of the received signal into a digital value, and outputs the digital value. When the significant signal is detected, the automatic gain control circuit determines any one of predetermined coarse gain intervals to be a first coarse gain interval of the received signal by taking into account the magnitude of the received signal detected by the RF power detection circuit."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Bluetooth smart signal receiving method and device using improved automatic gain control","description":"Disclosed herein are a Bluetooth signal receiving device and method.
