Title: Rob Abbott: Innovator in Digital Signal Processing

Introduction

Rob Abbott is a prominent inventor based in California, known for his significant contributions to digital signal processing. With a total of 8 patents to his name, Abbott has made remarkable advancements in the field, particularly in equalization techniques that enhance signal integrity.

Latest Patents

Among his latest patents is the "Multi-tap decision feed-forward equalizer with precursor and postcursor taps." This innovative configuration utilizes decision outputs from slicers as inputs to a finite impulse response (FIR) filter, resulting in reduced noise and crosstalk compared to traditional Feedforward Equalizers (FFE). The digital outputs from the tentative decision slicers are multiplied with tap coefficients, effectively simplifying the implementation of the multipliers. The equalized signal produced can then be used as input for subsequent stages, leading to improved bit-error-rate (BER) performance.

Another notable patent is the "SerDes receiver with optimized CDR pulse shaping." This system features a slicer that provides an initial set of tentative decisions to a decision feedforward equalizer, which then produces a fully equalized output signal. The optimized pulse shaping enhances the quality of tentative decisions, ensuring that the clock data recovery system samples the signal at the ideal location.
