    Abstract: A gain controller sets a gain code indicating an optimum gain, a cutoff frequency code indicating a cutoff frequency, and a number of bits code indicating a number of bits. An AEQ/VGA gain controller sets a frequency characteristic code indicating a frequency characteristic, a gain code indicating a gain after correction, and a number of bits code indicating a number of bits. An AEQ/VGA amplifies a baseband received signal on the basis of a gain code and corrects a frequency characteristic of the baseband received signal on the basis of a frequency characteristic code. An HPF cuts off a band below a cutoff frequency of an output signal from the AEQ/VGA on the basis of a cutoff frequency code. An ADC quantizes an output signal from the HPF using a number of bits based on a number of bits code and generates a digital received signal.

    Abstract: A Variable Gain Amplifier (VGA) amplifies an input signal according to a gain, to produce an amplified signal. A detector module detects a power indicative of a power of the amplified signal. A comparator module compares the detected power to a high threshold, a low threshold and a target threshold intermediate the high and low thresholds. A controller module changes the gain of the VGA so as to drive the detected power in a direction toward the middle threshold when the comparator module indicates the detected power is not between the high and low thresholds.

    Abstract: A method and apparatus for generating the adaptive gain control signals in a communications receiver is disclosed. The present invention can be used with existing two stage gain architectures, and overcomes many undesirable characteristics of the previous mechanism. An apparatus is presented wherein each of a plurality of RF AGC gain controllable amplifiers are individually controlled by individual AGC control signals generated by an AGC controller so that the level of the output signal from each of the RF AGC gain controllable amplifiers is individually optimized for tuner performance.
