  • Patent number: 8018288
    Abstract: Embodiments of a high-linearity low-noise amplifier (LNA) are generally described herein. Other embodiments may be described and claimed. In some embodiments, an RF input signal may be amplified with a cascode amplifier. The cascode amplifier may include integrated notch filters to attenuate undesired signals. The cascode amplifier may operate from a large power supply when blockers are present to avoid voltage swing compression at its output. The cascode amplifier may be biased and designed to operate in a class AB mode to produce linear output current to avoid current compression or excessive current expansion.

  • Patent number: 7961056
    Abstract: Embodiments of the present invention include a low phase noise oscillator circuit using a current-reuse technique to reduce power consumption and improve phase noise, where the oscillator circuit comprises a first VCO coupled to a second VCO, and the outputs of the first and second VCOs are coupled with passive elements, such as capacitors. The overall power consumption of both the first and second VCOs is about the same as a single VCO. Furthermore, the phase noise is lowered by around 3 dB. Thus, the phase noise performance is improved without increasing the power consumption of the oscillator circuit.

  • Patent number: 7676213
    Abstract: A gate-to-source voltage (Vgs) replication circuit includes a diode-connected NMOS transistor coupled to a current source to draw a drain-to-source current therethrough. The generated Vgs is imposed across a source-to-gate junction of a PMOS transistor. A second PMOS transistor is coupled in series with the first PMOS transistor such that the source-to-gate voltage (Vsg) of the second PMOS transistor replicates the Vgs of the NMOS circuit. The second PMOS transistor is coupled as a source follower to bias other NMOS transistors.

  • Patent number: 7505742
    Abstract: An operating voltage applied to a transmitter's power amplifier in a mobile wireless transceiver is dynamically controlled so as to improve the efficiency of the transmitter at all output power levels. In one embodiment, the bias current levels within the transmitter are also varied to optimize the efficiency of the transmitter at all output power levels. In a preferred embodiment, a highly efficient switching regulator is controlled by a control circuit to adjust the operating voltage and/or bias current for the power amplifier in the transmitter. The control circuit has as its input any of a variety of signals which reflect the actual output power of the transmitter, the desired output power, or the output voltage swing of the transmitter.
