He has made significant contributions to the field of digital phase-locked loops (DPLLs) and has been awarded 5 patents for his innovative work. His expertise lies in developing advanced circuits that enhance the performance and efficiency of digital systems.

Latest Patents

One of Avri's latest patents is titled "Independently clocking digital loop filter by time-to-digital converter in digital phase-locked loop." This invention features a time-to-digital converter (TDC) circuit that calculates phase error values based on the time difference between an input reference clock and a feedback clock of a DPLL circuit. The TDC circuit also includes clock generation circuitry that generates a filter clock, ensuring synchronization with the phase error values provided to the digital loop filter (DLF).

Another notable patent is the "Sigma-delta modulator for high-resolution control of ring oscillator in digital phase-locked loop." This invention involves a digitally-controlled oscillator (DCO) circuit that utilizes a digital-to-analog converter (DAC) to generate a first current based on the most significant bits of a multi-bit code received from a TDC. The DCO circuit also incorporates a sigma-delta modulator (SDM) to modulate the least significant bits of the multi-bit code, allowing for precise control of the ring oscillator's output signal.
