  • Wideband inductor-less balun-LNA with improved pickup noise rejection
    Patent number: 9143109
    Abstract: An inductor-less balun low-noise amplifier (LNA) includes a cross-coupled network coupled between first and second input terminals and first and second summing nodes. The cross-coupled network may include: a first non-inverting gain stage coupled between the first input terminal and the first summing node; a first inverting gain stage coupled between the first input terminal and the second summing node; a second non-inverting gain stage coupled between the second input terminal and the second summing node; and a second inverting gain stage coupled between the second input terminal and the first summing node. The cross coupled network may be configurable to provide common-mode rejection when operated in a differential or in a single-ended mode of operation.

  • Biasing scheme for low supply headroom applications
    Patent number: 7030687
    Abstract: Methods and apparatus for improving the current matching within current mirror circuits in applications such as low voltage integrated circuits. Embodiments of the present invention attempt to maintain the proper current ratio between reference and output supplies by adjusting the reference output of the current mirror. An existing reference voltage on the output side of the mirror can be used or a reference voltage can be created to be used for the voltage regulation of the reference side of the current mirror.
