Title: The Innovative Journey of Ken Suyama

Introduction

Ken Suyama, an accomplished inventor based in Mamaroneck, NY, has made significant contributions to the field of electrical engineering with a remarkable portfolio of seven patents. His innovative work primarily focuses on the advancement of phase-locked loops (PLLs) in digital circuits, which have widespread applications in communication systems, computing, and signal processing.

Latest Patents

Among his notable patents, Ken's recent innovation, “PLL Circuit with Improved Phase Difference Detection,” stands out. This patent introduces a sophisticated technique for enhancing phase difference detection, particularly when the phase difference approaches zero. The design incorporates a feedback loop consisting of a phase frequency detector (PFD), a time-to-digital converter (TDC), a digital low-pass filter (DLF), and a digitally controlled oscillator (DCO). This system skillfully manages high-frequency noise components and ensures accurate phase control of the feedback signal. By adding an offset value in various segments of the feedback loop, the technology guarantees that a non-zero value is inputted to the TDC, even when the all-digital PLL is locked, thus improving the overall performance and reliability of the circuit.
