  • Amplification circuit
    Patent number: 9214908
    Abstract: An amplification circuit (100) comprising a first filter (102) and an LNA (110). The first filter (102) comprising an input (104) for receiving an input signal; a first differential output (106); and a second differential output (108). The first filter (102) has a differential mode of operation for frequencies in its pass-band (706, 806) and a common mode of operation for frequencies outside its pass-band (706, 806), and may be an acoustic wave filter. The LNA (110) comprising a first differential input (112) connected to the first differential output (106) of the first filter (102); a second differential input (114) connected to the second differential output (108) of the first filter (102); and an output (116) for providing an amplified output signal.
    Type: Grant
    Filed: July 29, 2014
    Date of Patent: December 15, 2015
    Assignee: NXP, B.V.
    Inventors: Marcel Geurts, Louis Praamsma, Michel Groenewegen, Rainier Breunisse, Freek van Straten, Robert Buytenhuijs

  • Gilbert mixer
    Patent number: 8536926
    Abstract: A Gilbert mixer (200) comprising four switching transistors (Q3, Q4, Q5, Q6), two intermediate frequency transistors (Q1, Q2), and one or more DC decoupling components (202). The one or more DC decoupling components (202) are coupled between the switching transistors (Q3, Q4, Q5, Q6) and the intermediate frequency transistors (Q1, Q2) in order to DC decouple the switching transistors (Q3, Q4, Q5, Q6) from the intermediate frequency transistors (Q1, Q2).
