Title: Eric P Mitchell: Innovator in Phase Locked Loop Technology

Introduction

Eric P Mitchell is a notable inventor based in Milpitas, CA (US). He has made significant contributions to the field of electronics, particularly in the development of phase locked loop (PLL) technology. With a total of 6 patents to his name, Mitchell's work has had a considerable impact on the industry.

Latest Patents

One of his latest patents is for a Phase Locked Loop operable over a wide frequency range. This innovative PLL maintains a substantially constant gain across various frequency ranges. The design divides the frequency range into multiple sub-ranges, allowing for an adjustable loop gain profile as the PLL transitions between these sub-ranges. This ensures that when the PLL switches to a new frequency sub-range, the loop gain profile is adjusted to a pre-established value, facilitating smooth frequency changes within each sub-range.

Another significant patent by Mitchell is a circuit and method to eliminate startup and shutoff runt pulses from crystal oscillators. This circuit design prevents the generation of runt pulses when the oscillator is powered on or off. It includes a crystal oscillator, an integrator that accumulates energy from multiple pulses, and a threshold circuit that activates when the integrator's output reaches a specified threshold. Gating circuits then control the output of the crystal oscillator, ensuring that it only reaches the output terminal once the threshold condition is met.
