Title: Christopher W. Dix: Innovator in Programmable Logic Devices
Introduction
Christopher W. Dix is a notable inventor based in Hillsboro, OR (US). He has made significant contributions to the field of programmable logic devices, holding a total of 2 patents. His work focuses on enhancing the efficiency and reliability of electronic assemblies.
Latest Patents
One of his latest patents is titled "Hotswap operations for programmable logic devices." This invention provides techniques to control hotswap operations with programmable logic devices (PLDs). Specifically, it introduces a MOSFET designed to limit in-rush current drawn from a power supply by capacitive components when plugged into a live power supply. A controller with an algorithm is utilized to manage the MOSFET based on the detected in-rush current. This establishes a feedback control loop that selectively biases the gate of the MOSFET according to the in-rush current detected. The algorithm can limit the in-rush current based on the Safe Operating Area (SOA) of the MOSFET, transitioning through multiple phases with respective voltage and current limits during the hotswap process.
Another significant patent is "Power supply remote voltage sensing." In this invention, two transistors are simultaneously controlled by a controller to manage the application of power to a load while monitoring the voltage level at that load. The controller can apply power to multiple loads simultaneously and provide voltage tracking for these loads.
