  • Patent number: 8149053
    Abstract: The present invention relates to a low noise amplifier comprising a transformer, a first amplifier and a feedback resistor, the transformer comprising a primary stage and a secondary stage. The secondary stage is connected to the input of the first amplifier and the output of the first amplifier is connected in series with a feedback resistor and the primary stage of said transformer.

  • Patent number: 7116177
    Abstract: A PLL circuit with a series coupling of a charge pump, a loop filter and a voltage-controlled oscillator generating an output frequency (f), the voltage-controlled oscillator including tunable devices controlled by a first control signal generated by the loop filter, the PLL circuit includes a leakage compensation circuit for generating a leakage compensation signal to modify a control of the voltage-controlled oscillator, the leakage compensation signal being indicative for a leakage current in the tunable devices of the voltage-controlled oscillator.

  • Publication number: 20050174179
    Abstract: A PLL circuit (1) comprising a series coupling of a charge pump (10), a loop filter (20) and a voltage-controlled oscillator (30) generating an output frequency (f), said voltage-controlled oscillator (30) comprising tunable devices (C1, C2, C1?, C2, C3) controlled by a first control signal (Vt1) generated by the loop filter (20), the PLL circuit (1) being characterized in that it further comprises a leakage compensation circuit (40) for generating a leakage compensation signal (IL) to modify a control of the voltage-controlled oscillator (30), the leakage compensation signal (IL) being indicative for a leakage current in the tunable devices of the voltage-controlled oscillator (30).

  • Patent number: 6259903
    Abstract: Ordinarily, at least two types of mixer oscillator integrated circuits for tuners have to be used, i.e., one for the symmetrical output mode and one for the asymmetrical output mode. In order to handle both output modes, a tuner includes a switching circuit, whereby, in the asymmetrical mode, one output of the tuner is coupled to ground.

  • Patent number: 5887246
    Abstract: The circuit (7, 8, 9, 10) comprises, in addition to the automatic gain control (AGC), a gain reduction means for controlling the gain of an amplifier (8), intended to avoid the desynchronization of the local oscillator (7) controlled by a phase-locked loop comparator (12). This is controlled by a peak detector of the amplified signal situated at the output of the amplifier (8).
