Title: The Innovative Contributions of Jeffrey R. Fox
Introduction
Jeffrey R. Fox is a notable inventor based in Concord, MA (US), recognized for his significant contributions to the field of integrated circuits. With a total of 6 patents to his name, Fox has developed innovative solutions that enhance the functionality and reliability of electronic systems.
Latest Patents
Among his latest patents is the "Integrated Circuit Input-Output Diagnostic System." This invention focuses on input and output fault monitoring circuits that determine the presence of open connections at the input and output pads of integrated circuit chips. The input fault monitoring circuit operates on the principle that a lack of input signal throughout the known duty cycle indicates a defect, such as an open circuit interconnect. The output fault monitoring circuit generates a signal through a dummy circuit, which helps indicate the presence or absence of a disconnected output pad.
Another significant patent is the "Driver Circuit," which describes an MOS FET inverter driver circuit. This circuit includes a first depletion-type FET, a resistance formed by a depletion-type FET, and a second enhancement-type FET connected in series between a positive voltage source and ground. The design incorporates additional enhancement-type FETs to achieve high-speed operation and bootstrap action, providing high voltage drive to turn on the output pull-up transistor.
