Title: Robert Emile Van De Grift and His Analog-Digital Converter.
Introduction
Robert Emile Van De Grift is an inventor associated with Eindhoven, the Netherlands, and U.S. Philips Corporation. His recorded patent concerns the conversion of analog signals into digital form.
Latest Patents
Van De Grift is credited with 1 patent: “Analog-digital converter.” The invention uses transistor switches and a capacitor through which a continuous current flows, determined by an input difference voltage. A comparator connects one side of the capacitor to a clock-driven flip-flop, which controls the transistor switches. The other side connects to a differential amplifier in a negative-feedback loop, maintaining the voltage at its first input equal to the voltage applied to its second input.
Career Highlights
Van De Grift’s patent reflects work on electronic conversion circuitry, combining a capacitor, comparator, flip-flop, transistor switches, and differential amplifier in a feedback arrangement. The listed company associated with his work is U.S. Philips Corporation.
Collaborations
Theodorus J. Van Kessel and Abraham Hoogendoorn are identified as Van De Grift’s coworkers.
Conclusion
Robert Emile Van De Grift’s recorded contribution is an analog-digital converter design that uses feedback and switched capacitor circuitry to support signal conversion.
