Latest Patents
Norman M. Filiol holds a patent for a "Delta-sigma based dual-port modulation scheme and calibration techniques for similar modulation schemes." This patent describes PLL frequency synthesizers and their calibration techniques. The PLL frequency synthesizers are utilized to generate digital modulation of a carrier signal. A digital frequency divider in the feedback path of the loop has its division ratio controlled by a digital Δ-Σ modulator. The modulation of the carrier is achieved by applying a modulation signal to the input of the Δ-Σ modulator and to the input of the voltage-controlled oscillator of the PLL. The high frequency path and low frequency path of the modulation signal must be adjusted with respect to one another to obtain effective modulation. As the low frequency path can be accurately set, the calibration is performed only on the high frequency path. Digital calibration techniques for the high frequency path are also described in his patent.
