  • Patent number: 10523191
    Abstract: Aspects of methods and systems for high frequency signal selection are provided. The system for high frequency signal selection comprises a first driver and a second driver. The first driver is able to receive a first high frequency input, and the second driver is able to receive a second high frequency input. The output of the first driver is operably coupled, via a first inductive element, to a first resistive load and a first buffer, and the second driver is operably coupled, via a second inductive element, to the output of the first driver. One or both of the first high frequency input and the second high frequency input may be transferred to the first buffer by selectively enabling a current to one or both of the first driver and the second driver, respectively.

  • Patent number: 10181869
    Abstract: Methods and systems for a configurable low-noise amplifier with programmable band-selection filters may comprise a receiver with a low-noise amplifier (LNA) with first and second input terminals and differential output terminals; a low pass filter operably coupled to the LNA; a high pass filter operably coupled to the second input terminal of the LNA; and a signal source input coupled to the low pass filter and the high pass filter. The LNA may be operable to receive signals in a pass band of the high pass filter and a pass band of the low pass filter. The receiver may be operable to amplify input signals in the pass band of a first filter but not signals in the pass band of the second filter by operably coupling the second to ground.
