摘要： With advanced compute capabilities and growing convergence of wireless standards, it is desirable to run multiple wireless standards, e.g., 4G, 5G NR, and Wi-Fi, on a single signal processing system. Automatic gain control (AGC) is a process of converging on a gain level for optimum signal reception considering the dynamic range of all the components in the receive chain, including analog and digital parts. For certain wireless standard such as Wi-Fi, AGC is required to complete within a short interval. Both RF and baseband gains have to be adjusted within this short time. Discloses in the present disclosure are embodiments of a high-speed and low pin-count interface between an RF circuit and a baseband circuit for AGC communication. The high-speed interface provides a light-weight serial protocol over one or more low-voltage differential signaling (LVDS) channels to meet a low-latency requirement for gain updates.

摘要： A near-field communication (NFC) antenna structure for radiation enhancement of a computing device (102) that includes a ferrite sheet (208), separated into two sections. The NFC antenna structure is used to improve the magnetic field strength generated by an NFC antenna and inductive coupling to a receiving antenna of another computing device. A first ferrite section (210-1) is placed on a first side of the NFC antenna to at least partially overlap the NFC antenna, and a second ferrite section (210-2) is placed on a second side (opposite the first side) to at least partially overlap the NFC antenna. The first ferrite section (210-1) is positioned towards a top end that is often positioned closest to a receiving device, as held by a user when performing a contactless communication of the computing device (102), to increase the magnetic field strength and improve the inductive coupling at the top end.
