Title: The Innovations of Norman R. Scheinberg
Introduction
Norman R. Scheinberg is a notable inventor based in South River, NJ (US). He has made significant contributions to the field of integrated circuits, particularly in the development of upconverter chips for cable television receivers. With a total of four patents to his name, Scheinberg's work exemplifies innovation in electronic engineering.
Latest Patents
Scheinberg's latest patents include a low-cost monolithic gallium arsenide upconverter chip. This innovative integrated circuit performs the first frequency conversion of a dual conversion cable television (CATV) receiver. The upconverter chip consists of three functional blocks: a Gilbert type image-rejecting mixer, a phase splitter, and a voltage-controlled oscillator. The mixing process is enhanced by a novel Gilbert type mixer that incorporates image-rejection inductors, improving the noise figure of the mixer. Additionally, a differential circuit topology allows the chip to utilize a plastic dual inline batwing package without significant performance loss. On-chip RF bypass networks, in the form of series RC terminations, help mitigate the undesirable effects of pin inductances in the dual inline package. Furthermore, a resistor-based DC biasing scheme dramatically reduces power-up latency, facilitating faster testing.
