Title: Douglas Jw Macfarlane and Voltage-Monitored Switching Drivers.
Introduction
Douglas Jw Macfarlane is an inventor associated with Edinburgh, Great Britain, and Cirrus Logic Inc. His listed patent concerns switching-driver technology that monitors voltage conditions and compensates for variations to support reliable output control.
Latest Patents
Macfarlane is listed as an inventor on 1 patent: “Switching Drivers with Voltage Monitoring.” The application describes a switching driver with two switches that selectively connect an output node to two switching voltages to generate an output voltage. A compensator receives monitor signals indicating the sum and difference of those voltages, then adjusts the input signal to account for deviations from defined nominal values. A modulator uses the compensated input signal to control the switches’ duty cycle.
Career Highlights
The available information associates Macfarlane with Cirrus Logic Inc. and identifies his work on voltage monitoring and compensation in switching drivers. The patent’s approach is designed to address variations in switching voltages through signal compensation and duty-cycle control.
Collaborations
John L. Melanson is identified as Macfarlane’s coworker. The provided information does not specify whether Melanson collaborated on this patent.
Conclusion
Douglas Jw Macfarlane’s listed patent focuses on compensating for switching-voltage variations, highlighting a practical approach to controlling switching-driver output.
