Introduction

Charles E Berndt is a notable inventor based in Nepean, Canada. He has made significant contributions to the field of digital communications, holding two patents that showcase his innovative techniques. His work primarily focuses on enhancing the efficiency and effectiveness of digital loop filters and decision feedback equalizers.

Latest Patents

One of Berndt's latest patents is titled "Techniques for Digital Loop Filters." This invention involves a digital loop filter that includes both a fine control circuit and a coarse control circuit. The fine control circuit adjusts the phase of a feedback clock signal based on a first phase error signal, while the coarse control circuit makes larger adjustments based on a second phase error signal. This dual approach allows for more precise control of the feedback clock signal.

Another significant patent is the "Blind Adaptive Decision Feedback Equalizer for High-Speed Serial Communications." This technique utilizes two thresholds to determine the validity of incoming sampled analog data. If the signal magnitude exceeds the first threshold, it is deemed valid; otherwise, it is considered erroneous. This method reduces processing demands by ensuring that not every sample generates an error signal. The second threshold, known as the block threshold, dictates when the filter coefficients are updated based on accumulated errors, further optimizing processing efficiency.
