  • Amplifier circuit with adjustable amplification
    Patent number: 7737785
    Abstract: An amplifier circuit has an amplifier element having an amplifier element input and an amplifier element input impedance, an amplification adjuster adapted to adjust an amplification of the amplifier element, an amplifier circuit input coupled to the amplifier element input, an impedance element having a alterable impedance value and being coupled to the amplifier circuit input, and an impedance adjuster adapted to adjust the impedance value of the impedance element as a function of the amplification of the amplifier element.
    Type: Grant

  • Frequency generator with a phase locked loop
    Patent number: 7218178
    Abstract: A frequency generator with a phase locked loop includes a loop filter, the transfer function of which has a pair of complex conjugated poles. The present invention provides an optimum and greatly improved compromise, in particular as opposed to the prior art, between phase noise and settling time of the phase locked loop of the frequency generator.
