Technical Examples

Aspects of the invention provide a method and system for a mixed analog-digital automatic gain control. The received analog signal is amplified by the analog amplifier and then converted to a digital value by an ADC. A clamp reference level of the converted signal is removed prior to applying a digital gain to a digital multiplied. Once the digital gain is applied, the clamp reference level is restored to the digital signal. A loop filter determines the system time response from the error between an amplitude parameter of the received signal and an AGC reference level. A gain separation circuit generates the system gain and separates it into a digital gain and an analog gain in a way to maximize the use of the analog amplifier. The analog gain is applied to the analog amplifier and the digital gain is applied to the digital multiplier.
