Title: The Innovations of Stefan Barkarö

Introduction

Stefan Barkarö is a notable inventor based in Åkersberga, Sweden. He has made significant contributions to the field of electronics, particularly in the area of signal processing. His innovative work has led to the development of a unique patent that addresses challenges in line driver/receiver circuits.

Latest Patents

Stefan Barkarö holds a patent for an "Echo canceling arrangement." This invention is designed for a line driver/receiver circuit where the line driver connects its output terminals to a load for supplying a transmit signal. The receiver simultaneously receives a receive signal from the load. The transmit signal on the input terminals of the receiver is canceled by connecting the output terminals of the line driver to the load via equal complex sense impedances. These impedances have a value much smaller than that of the load impedance, allowing for effective matching. The input terminals of the receiver are connected to the load via equal first resistors and to the respective output terminal of the line driver via equal second resistors. Additionally, transconductance amplifiers are provided to sense the voltage across the sense impedances and supply corresponding currents to the respective input terminal of the line driver.
