  • Radio receiver having enhanced automatic gain control circuitry
    Patent number: 9735748
    Abstract: An apparatus includes an input terminal to receive a radio frequency (RF) signal and to communicate the RF signal to a low noise amplifier (LNA) via an input signal path, and a capacitor attenuator coupled to the input terminal to attenuate the RF signal by a controllable amount and having a first portion controllable to include a used part configured on the input signal path and an unused part coupled between the input signal path and an AC reference node, and a second portion coupled between the LNA and the AC reference node.
    Type: Grant
    Filed: December 15, 2015
    Date of Patent: August 15, 2017
    Assignee: Silicon Laboratories Inc.
    Inventors: Mark May, Steve Hanawalt
