    摘要: In one embodiment, the present invention includes an amplifier having a transistor stage coupled between a supply voltage and a bias current. The transistor stage has an input to receive a radio frequency (RF) input signal obtained from an antenna. The amplifier has an input impedance that is unmatched to a source impedance of the antenna. In some embodiments, this unmatched input impedance may be substantially greater than the source impedance, and may further be controlled based on a strength of the RF input signal.

    摘要: In one embodiment, the present invention includes a single chip radio tuner, which may be adapted within an integrated circuit (IC). The tuner may be provided with a configurable front end to receive and process a radio frequency (RF) signal via a signal path. This configurable front end may be differently controlled depending on a particular radio implementation in which the tuner is adapted.

    摘要: 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.
