Title: Bobby L Barnes: Innovator in Ultra Wideband Technology
Introduction
Bobby L Barnes is a notable inventor based in Cambridge, MA, who has made significant contributions to the field of ultra wideband (UWB) technology. With a total of two patents to his name, Barnes has developed innovative systems and methods that enhance the performance of UWB receivers.
Latest Patents
Barnes' latest patents focus on calibrating an analog signal path during operation in an ultra wideband receiver. The first patent presents a system and method for calibrating an analog signal path associated with a UWB receiver. This system includes multiple analog gain stages, a local oscillator mixer stage, a compensation stage, and a converter stage. The method involves accumulating a predetermined number of whitened symbols for one of the gain configurations, calculating an arithmetic mean, and using this value as an offset to improve signal accuracy.
The second patent also addresses the calibration of an analog signal path in a UWB receiver. In this case, a frequency offset of 4 MHz is applied to a local oscillator signal to minimize correlation between the received signal and the local oscillator signal. The method involves activating one of the analog gain stages and storing an offset obtained at the converter stage as a compensation value. This compensation value is then retrieved and applied during normal processing to further reduce any offset.
