Introduction

Aleksander Dec, an accomplished inventor based in Tarrytown, NY, has made significant contributions to the field of digital circuit design with a total of seven patents to his name. His innovative spirit and technical expertise have allowed him to enhance various technologies, particularly in the realm of phase-locked loops (PLLs).

Latest Patents

One of Aleksander's latest patents focuses on a PLL circuit with improved phase difference detection. This invention introduces a technique to enhance phase difference detection in close proximity to zero phase difference within an all-digital adaptive PLL (ADPLL). The innovation features a feedback loop that includes a phase frequency detector (PFD) that compares the phases and frequencies of both a reference signal and a feedback signal. Further advancements in this patent include a time-to-digital converter (TDC) that translates the PFD output into a digital value, and a digital low-pass filter (DLF) that minimizes high-frequency noise from the TDC output. The digitally controlled oscillator (DCO) is adjusted according to the DLF output, while a divider (DIV) generates the feedback signal. A key element of this development is the addition of an offset value at any stage of the feedback loop, which allows for controlled phase adjustments, even when the ADPLL is in a locked state.
