Abstract: A ratiometric clock system for an integrated receiver and associated method are disclosed that provide an advantageous solution for combining digital signal processing (DSP) circuitry on the same integrated circuit as mixer and local oscillator (LO) generation circuitry. The generation circuitry generates an oscillation signal that is passed through a first divider to generate mixing signals for the mixer and that is passed through a second divider to generate a digital clock signal that is utilized by the DSP circuitry. This digital clock signal can be utilized by integrated analog-to-digital conversion circuitry, as well.

Abstract: In one embodiment, the present invention includes an amplifier having an input to receive a radio frequency (RF) signal from an output node of a source. An input stage coupled to the amplifier input may include one or more components to aid in processing of incoming signals. One such component coupled between the source and the input of the amplifier is a coupling capacitor used to maintain a bias voltage of the amplifier at a different potential than a DC voltage of the output node. In certain applications, the amplifier and the coupling capacitor may be integrated on a single substrate.

Abstract: On-chip calibration signal generation circuitry is disclosed for filter tuning for radio-frequency communications and associated methods. On-chip circuitry generates a calibration signal that is used to help set a tuning control signal that is received by a tunable front-end filter. In one embodiment, local oscillator (LO) generation circuitry is used to generate the calibration signal. In operation of this embodiment, the LO generation circuitry is tuned to the desired receive channel, or to a frequency at some offset value from the desired receive channel, and the output of the LO generation circuitry is then used as a calibration input signal for a tunable front-end filter. This calibration signal is passed through the receive path circuitry, and the resulting signal is then analyzed to help set a tuning control signal for the tunable front-end filter.
