  • Patent number: 8873676
    Abstract: Embodiments provide improved systems and methods of gain control and calibration for wireless transmitters. In particular, embodiments allow linear gain control over the entire transmitter gain control range, independent of temperature/process variations. Embodiments require very low power consumption compared to existing approaches. Embodiments may also be used for gain control calibration during production time, thereby substantially reducing production calibration time and cost.

    Abstract: A system for processing a signal is provided. The system includes a differential amplifier receiving a radio-frequency input signal at a first differential input. A rectifying device such as a transistor has a control terminal that is coupled to an output of the differential amplifier and an output that is coupled to a second differential input of the differential amplifier. The second differential input of the differential amplifier receives a low frequency feedback signal from the output of the rectifying device, such as by damping the frequency response at the output of the rectifying device using a capacitor and a current source coupled to the output of the rectifying device.

  • Patent number: 7612617
    Abstract: A phase-locked loop (PLL) is arranged to receive high-pass data at a first input and low-pass data at a second input. A first digital input is coupled to a primary path through a digital-to-analog converter (DAC) and a second digital input is coupled to a feedback path of the PLL. The controller provides the first input and the second input during a calibration procedure. The controller adjusts first and second control inputs in an attempt to keep the input voltage to a voltage-controlled oscillator (VCO) in the PLL constant while determining the gain of the VCO in Hz/LSB.
