Title: Rocco J Robortaccio: Innovator in Bi-Directional Transceiver Circuits
Introduction
Rocco J Robortaccio is a notable inventor based in Hopewell Junction, NY (US). He has made significant contributions to the field of electronics, particularly in the development of advanced circuit designs. With a total of 3 patents to his name, Robortaccio's work has had a lasting impact on the industry.
Latest Patents
One of his latest patents is a bi-directional transceiver circuit. This invention describes a simultaneous bi-directional transceiver that comprises two circuits located at opposite ends of an interchip cable. In response to the application of digital data signals to these circuits, they generate a trilevel voltage at the ends of the interchip cable. Each circuit generates a first input to a differential amplifier from the trilevel voltage using a level shifter with a diode and a constant current sink. The second input to the differential amplifier is derived from the digital data input signal through another level shifter. The transceiver outputs are then generated from the differential amplifier outputs.
Another significant patent is a TTL logic circuit employing feedback to improve the speed-power curve. This invention adds passive feedback to a prior art T²L circuit, resulting in lower power dissipation while maintaining noise immunity and small gate delay. The additional resistor required for the feedback T²L circuit can be incorporated without increasing the cell size. This innovation allows for more functions to be placed on an integrated circuit semiconductor chip while adhering to power restrictions.
