Patent ID: 8711288

Claim:
An integrated digital intermediate frequency (IF) demodulator, comprising: an analog input section configured to: receive an analog signal having a carrier frequency embedded within a desired channel of the analog signal, and amplify the received analog signal to provide an amplified analog signal via a first voltage gain amplifier (VGA); and convert, via an analog to digital converter (ADC), the amplified analog signal to a digital signal using a sampling frequency that is less than a frequency of the analog signal received by the ADC, the digital signal being frequency translated to an IF; an automatic gain control (AGC) circuit configured to generate a first output and a second output based on a magnitude of the frequency translated digital signal, the first output being provided to control a gain of the first VGA and the second output being provided to control a gain of a second VGA; a digital signal processing (DSP) block, coupled to the analog input section, configured to truncate a desired channel within the frequency translated digital signal and to frequency translate the desired channel within the frequency translated digital signal to a baseband frequency; and a substrate, wherein the DSP block and the analog input section are disposed on the substrate.
