Title: The Innovations of Norman Hugo Walker

Introduction

Norman Hugo Walker is a notable inventor based in San Diego, CA. He has made significant contributions to the field of electronics, particularly in the area of calibration systems for Phase Locked Loops (PLLs). His work has implications for improving the performance and reliability of various electronic devices.

Latest Patents

Walker holds a patent for a "Coarse calibration circuit using variable step sizes to reduce jitter and a dynamic course calibration (DCC) circuit for a 2 GHz VCO." This innovative calibration system includes a phase/frequency detector that is coupled to the output of a voltage-controlled oscillator (VCO) and a source of reference frequency. The system utilizes a charge pump to receive an error signal from the phase/frequency detector, which then provides a voltage to a low pass filter. The filtered error signal is sent to the VCO and a comparator system, which indicates when the error signal exceeds certain limits. This continuous calibration process helps to correct the frequency of the VCO in the PLL, compensating for frequency drift and minimizing jitter.
