Title: Innovations of Augusto Ronchini Ximenes
Introduction
Augusto Ronchini Ximenes is a notable inventor based in The Hague, Netherlands. He has made significant contributions to the field of frequency synthesis and digital signal processing. With a total of 4 patents, his work focuses on enhancing the efficiency and performance of digital phase-locked loops.
Latest Patents
Ximenes' latest patents include a "Fractional-N frequency synthesizer incorporating cyclic digital-to-time and time-to-digital circuit pair." This innovative look-ahead time to digital converter (TDC) is applied to an all-digital phase-locked loop (ADPLL) as the fractional phase error detector. The design exploits the deterministic nature of the phase error during frequency and phase lock to reduce power consumption. The look-ahead TDC circuit constructs a cyclic DTC-TDC pair that minimizes fractional spurs in the output spectrum of near-integer channels. By randomly rotating the cyclic DTC-TDC structure, it starts from different points with each reference clock, averaging out element mismatches. Associated rotation and dithering methods are also presented, enhancing the ADPLL's performance.
Another significant patent is the "Fractional-N all digital phase locked loop incorporating look ahead time to digital converter." This patent shares similar features with the previous one, emphasizing the reduction of power consumption and the improvement of output spectrum quality through innovative circuit design.
