  • Automatic gain control circuit and an RF receiver and method using such a circuit
    Patent number: 7065335
    Abstract: An automatic gain control (AGC) circuit including: a forward transmission path (214) having applied at its input an input RF signal and to provide at its output an output signal; a variable gain AGC amplifier (210) in the forward transmission path for processing the input RF signal, which amplifier has a control input 240 and is responsive to a control signal applied at its control input to vary its gain; a feedback loop (220 to 240), coupled from the output of the forward transmission path and to the control input of the AGC amplifier; an integrator (230, 232), coupled to the control input of the amplifier; a voltage source (234), coupled to the integrator and to the control input of the amplifier; and a further variable gain device (215) for varying the gain or attenuation of a signal applied to the control input of the AGC amplifier.
