摘要： A receiver circuit includes a quadrature passive mixer, a first charge load, and a second charge load. The quadrature passive mixer has a differential input for receiving a differential input signal, and arranged for mixing the differential input signal with a quadrature local oscillator (LO) signal. The quadrature passive mixer has an in-phase mixer with a differential in-phase output, and a quadrature-phase mixer with a differential quadrature-phase output. The first and second charge loads are coupled to differential in-phase output and differential quadrature-phase output, respectively. In every quarter cycle of the quadrature LO signal, the differential in-phase output and the differential quadrature-phase output are arranged to be not shorted so as to avoid charging sharing between the first charge load and the second charge load, or are arranged to be shorted to cause charging sharing between the first charge load and the second charge load that generates a leakage path.

摘要： A receiver front end is provided with a low-noise amplifier (LNA), a linearity on demand (LOD) circuit, and a gain calibration device. The LOD circuit provides current to the LNA depending on linearity requirements. The gain calibration device monitors the amount of current provided by the LOD circuit to the LNA and provides signals to help compensate for variations in the LNA's gain due to the variations in the current supplied to the LNA by the LOD circuit. The compensation signals may be used to adjust the gain of a variable-gain amplifier, or may comprise compensation parameters usable by a digital signal processor, to compensate for the gain variations.

摘要： Embodiments of the invention provide techniques for calibrating voltage-controlled oscillators (VCOs). Multiple VCOs may be disposed on a chip with the VCOs having different frequency ranges. The VCOs may be selected and tested to determine a desired VCO to use to tune to a selected channel frequency. Each of the VCOs has multiple possible varactor configurations. The varactor configurations of the desired VCO determined to be used to tune to the selected channel frequency can be selected and tested to determine a desired varactor configuration for the desired VCO. The desired VCO with the desired varactor configuration will preferably be able to produce a full range of desired frequencies corresponding to all channel frequencies desired.

摘要： Systems for controlling the amplitude of the output signal of a controllable oscillator in a frequency synthesizer are provided. One such system provides a circuit having a controllable oscillator and an amplitude control circuit. The controllable oscillator is configured to generate an output signal having a predefined frequency and a predefined amplitude. The controllable oscillator is also configured with a plurality of operational states that are controlled by the amplitude control circuit. Each operational state of the controllable oscillator defines a particular current bias associated with a distinct amplitude of the output signal of the controllable oscillator. The amplitude control circuit receives the output signal of the controllable oscillator and determines the amplitude. When the amplitude of the output signal of the controllable oscillator is less than the predefined amplitude, the amplitude control circuit provides a control signal to the controllable oscillator. The control signal is configured to change the controllable oscillator to the operational state corresponding to the distinct amplitude that best approximates the predefined amplitude.
