  • Harmonic cancellation for frequency conversion harmonic cancellation
    Patent number: 8666352
    Abstract: A radio frequency (RF) receiver, such as a television tuner, includes a harmonic cancellation circuit. The harmonic cancellation circuit includes a primary signal path to generate a first intermediate frequency (IF) signal by mixing an RF signal with a reference signal and a harmonic feedforward signal path to generate a second IF signal representing signal content of the RF signal near an nth-order harmonic of a frequency fLO of the first reference signal, n comprising a positive integer. The harmonic cancellation circuit further includes a summation stage to generate a third IF signal based on a difference between the first IF signal and the second IF signal.

  • PLL lock management system
    Patent number: 7323944
    Abstract: A PLL includes a charge pump, a loop filter, a VCO, and a calibration unit. The calibration unit performs coarse tuning to select one or multiple frequency ranges, performs fine tuning to determine an initial control voltage that puts the VCO near a desired operating frequency, measures the VCO gain at different control voltages, and derives VCO gain compensation values for the different control voltages. The calibration unit also pre-charges the loop filter to the initial control voltage to shorten acquisition time, enables the loop filter to drive the VCO to lock to the desired operating frequency, and performs VCO gain compensation during normal operation. For VCO gain compensation, the calibration unit measures the control voltage, obtains the VCO gain compensation value for the measured control voltage, and adjusts the gain of at least one circuit block (e.g., the charge pump) to account for variation in the VCO gain.

  • Low-power direct digital synthesizer with analog interpolation
    Patent number: 7098708
    Abstract: An MN counter with analog interpolation (“MNA counter”) includes an MN counter, a multiplier, a delay generator, and a current generator. The MN counter receives an input clock signal and M and N values, accumulates M for each input clock cycle using a modulo-N accumulator, and provides an accumulator value and a counter signal with the desired frequency. The multiplier multiplies the accumulator value with an inverse of M and provides an L-bit control signal. The current generator implements a current locked loop that provides a reference current for the delay generator. The delay generator is implemented with a differential design, receives the counter signal and the L-bit control signal, compares a differential signal generated based on the counter and control signals, and provides the output clock signal. The leading edges of the output clock signal have variable delay determined by the L-bit control signal and the reference current.
