Patent ID: 7469137

Claim:
An integrated circuit radio receiver, comprising: amplification circuitry operable to receive RF signals and to produce amplified ingoing RF signals; mixing circuitry operable to produce IF signals based upon the amplified ingoing RF signals; a filtering block operable to filter the IF signals and to produce filtered IF signals; a multiple input programmable Continuous-Time Delta-Sigma Analog-to-Digital Converter (CTΔΣADC) coupled to receive the filtered IF signals, the programmable CTΔΣADC operable to produce digital data based on the filtered IF signals, wherein the programmable CTΔΣADC includes: a programmable input block operably coupled to receive an offset compensation control signal and operable to produce a scaled analog signal to compensate for a DC offset based upon the offset compensation control signal; and CTΔΣADC processing block operable to convert the filtered IF signals to digital data; digital IF demodulator operable to produce digital IF demodulated digital serial data based upon the digital data produced by the programmable CTΔΣADC; and DC offset compensation logic operable to produce an offset compensation control signal based upon a detected amount of DC in the digital IF demodulated digital serial data.
