Abstract: An automatic gain control loop disposed in a receiver is adapted to compensate for varying levels of out of band interference sources by adaptively controlling the gain distribution throughout the receive signal path. One or more intermediate received signal strength indicator (RSSI) detectors are used to determine a corresponding intermediate signal level. The output of each RSSI detector is coupled to an associated comparator that compares the intermediate RSSI value against a corresponding threshold. The take over point (TOP) for gain stages is adjusted based in part on the comparator output values. The TOP for each of a plurality of gain stages may be adjusted in discrete steps or continuously.

Abstract translation: 设置在接收机中的自动增益控制回路适于通过自适应地控制整个接收信号路径上的增益分布来补偿不同级别的带外干扰源。 一个或多个中间接收信号强度指示器（RSSI）检测器用于确定相应的中间信号电平。 每个RSSI检测器的输出耦合到相关联的比较器，其将中间RSSI值与相应的阈值进行比较。 增益级的接收点（TOP）部分基于比较器输出值进行调整。 可以以离散步骤或连续地调整多个增益级中的每一个的TOP。
