Title: Paul H Fontaine: Innovator in Analog-to-Digital Conversion and UWB Systems

Introduction

Paul H Fontaine is a notable inventor based in Plano, TX (US), recognized for his contributions to the fields of analog-to-digital conversion and ultra-wideband (UWB) systems. With a total of 8 patents to his name, Fontaine has made significant advancements that enhance the performance and efficiency of electronic systems.

Latest Patents

Among his latest innovations is the "Sigma-delta analog to digital converter with improved feedback." This invention features an input transconductance stage that generates an analog input current proportional to an analog input voltage. It also includes a current summing stage that produces an analog error signal, which corresponds to the difference between the analog input current and a feedback current. The converter processes this error signal to provide a digital output that accurately reflects the analog input voltage. Additionally, it incorporates a feedback path with a current steering digital-to-analog converter, allowing for steerable currents that directly provide the feedback current based on the digital output signal.

Another significant patent is the "Time-frequency interleaved orthogonal frequency division multiplexing ultra wide band physical layer." This invention utilizes the unlicensed 3.1-10.6 GHz UWB band, as regulated in the United States. It enables a wireless pico area network (PAN) with data payload communication capabilities ranging from 55 to 480 Mb/s. The system employs orthogonal frequency division multiplexing (OFDM) and utilizes 122 sub-carriers modulated using quadrature phase shift keying (QPSK), along with forward error correction coding.
