Title: The Innovations of Maurice V Whelan

Introduction

Maurice V Whelan is a notable inventor based in Eindhoven, Netherlands. He has made significant contributions to the field of semiconductor technology, holding a total of 3 patents. His work primarily focuses on the digitization of electric analog signals and the development of threshold circuits.

Latest Patents

One of Whelan's latest patents is a semiconductor device for digitizing an electric analog signal. This invention features an analog/digital converter implemented on a Metal-Insulator-Semiconductor (MIS) structure. The gate electrode is designed as a resistance layer across which a potential gradient is applied. The analog signal supplied to the gate electrode is converted into a shift of an inversion layer below the gate electrode. The digital signal is obtained by determining the number of surface regions present below the gate electrode that can be electrically connected to the inversion layer.

Another significant patent is a threshold circuit using complementary field effect transistors. This arrangement includes two complementary transistors whose channels are situated in series between two supply terminals. To achieve a square-wave relationship between the output voltage on the common drain electrodes and the input voltage on the interconnected gate electrodes, a direct voltage source is included between the two gate electrodes. This source has a voltage that is substantially equal to the supply voltage minus the sum of the threshold voltages of the two complementary transistors.
