Filter Circuit for Suppressing Signal Distortion

Simple SummaryContent extracted from patent full text and abstract with AI.

This patent describes a specialized filter circuit designed to prevent signal distortion caused by unwanted charge displacement in frequency splitters and current/voltage converters. By integrating a compensation circuit that detects and neutralizes the interfering signals at the hardware level, the invention delivers a clean, undistorted output signal, eliminating the need for complex post-processing. The method leverages either voltage or current measurements at specific points in the circuit to generate a compensation signal that effectively cancels out the distortion.

Patent Abstract

The invention relates to a filter circuit which is used, at the hardware level, to prevent charge displacements, which are caused by one or more currents in a frequency splitter (200), producing an interference signal which can cause signal distortion at the output of a current/voltage converter (300) belonging to the filter circuit. This signal distortion would otherwise have to be removed by means of complicated signal post-processing. The voltage profile at the input of the frequency splitter (200) or the current at the second output of the frequency splitter (200) is used in this case to model, by means of a compensation circuit arrangement, a compensation signal which substantially compensates for the interference signal caused by the charge displacements. The invention also relates to an associated method.
