  • Patent number: 8027657
    Abstract: A mixer 1100 with a plurality of signal paths typically requires separate clock generating hardware for each signal path. However, the redundancy of having multiple clock generating hardware significantly increases power consumption and integrated circuit area when the mixer 1100 is integrated into silicon. A method and apparatus 1125 containing a circuit for generating a set of clock signals that can be shared by the different signal paths is presented. Advantage is taken of the significant capacitance difference between different sampling capacitors in the mixer and the superposition property.
    Type: Grant

  • Patent number: 7023272
    Abstract: A low noise amplifier (LNA) operates over multiple frequency bands while occupying less silicon area than known LNA implementations. The LNA includes output matching that can be tuned by an adjustable inductor together with a tunable capacitor bank.
