Title: The Innovations of Roger J Cook

Introduction

Roger J Cook is a notable inventor based in Livonia, MI (US). He has made significant contributions to the field of electrical engineering, holding a total of 8 patents. His work primarily focuses on voltage regulation and line driver technologies, showcasing his expertise in creating efficient electronic systems.

Latest Patents

One of Roger's latest patents is the "Low Frequency Switching Voltage Pre-Regulator." This innovative device is designed to propagate low-frequency, low-power switching voltage. The pre-regulator consists of a chopping circuit, a pre-driver switching circuit, and a feedback circuit. The output of the chopping circuit defines the output of the voltage pre-regulator, receiving an input voltage at its input. The feedback circuit senses the voltage magnitude at the chopping circuit and generates a feedback signal accordingly. The PWM interface circuit processes these feedback signals along with a PWM signal typically derived from a microprocessor, enabling efficient switching of the chopping circuit.

Another significant patent is the "Low Side Line Driver." This device includes a slew rate limiter that provides current to a pre-charge reference circuit. The pre-charge reference circuit generates a constant voltage at the input of a pre-drive circuit. Upon transitioning to the active state, the pre-charge reference circuit is disabled, allowing current from the slew rate limiter to flow to the pre-drive circuit. This design minimizes propagation delay and high instantaneous slew rates, enhancing the performance of the output driver.
