Title: The Innovations of Keith Andrew Tilley

Introduction

Keith Andrew Tilley is a notable inventor based in Round Rock, TX (US). He holds a total of 9 patents that showcase his contributions to the field of technology, particularly in the area of transmitter circuits and DC offset correction methods. His work has significantly impacted the way signals are processed and transmitted.

Latest Patents

Among his latest patents is the "Transmitter circuit and method for modulation distortion compensation." This invention focuses on reducing amplitude modulation distortion in an amplifier. The transmitter circuit includes a power control error data generator, a feedforward predistortion data generator, feedforward adder logic, and the amplifier itself. The power control error data generator receives amplitude modulation data and an RF coupled output signal, producing power control error data in response. The feedforward predistortion data generator also receives the amplitude modulation data and generates feedforward predistortion data. The feedforward adder logic combines the power control error data and the feedforward predistortion data to produce power control data. This data is then used by the amplifier to reduce amplitude modulation distortion in the RF output signal.

Another significant patent is the "Smart DC offset correction loop," which describes a DC offset correction method and apparatus. In a differential system, this correction loop includes a gain stage with a differential input and output. A DAC circuit provides a correction DC signal at the inputs to produce differential output signals. A controller corrects the DC offset by adjusting the DAC circuit to change the correction DC signal accordingly. This innovative approach can also be applied to single-ended systems.
