Title: Wilhelmus H DeGuelle: Innovator in Transmission Systems and Voltage-to-Current Converters
Introduction
Wilhelmus H DeGuelle is a notable inventor based in Eindhoven, Netherlands. He has made significant contributions to the field of electrical engineering, particularly in the development of transmission systems and voltage-to-current converters. With a total of 2 patents, his work has had a considerable impact on modern technology.
Latest Patents
DeGuelle's latest patents include a transmission system using a transmitter with a phase modulator and frequency multiplier. This innovative system is designed for transmitting digital symbols by modulation according to a phase constellation. The transmitter features a phase modulator and a frequency multiplier in cascade, producing a modulated signal with a desired transmission frequency. To enhance the bit error rate, the phase constellation at the input of the phase modulator includes at least one additional phase state compared to the output of the frequency multiplier. Notably, the number of phase states at the input is N times that at the output, where N represents the frequency multiplication factor.
Another significant patent is a controllable voltage-to-current converter that utilizes MOS technology. This converter includes a signal resistor formed by a channel of a MOS signal transistor. The design incorporates a gate electrode for adjusting the resistance of the channel and a bulk electrode for connecting a bulk voltage. The supply system for the converter includes control circuitry that adjusts the bulk voltage in response to the gate voltage, effectively reducing third-order distortion.
