Title: Terence L Johnson: Innovator in Ultra Wideband Technology

Introduction

Terence L Johnson is a notable inventor based in Fairfax Station, VA (US). He has made significant contributions to the field of ultra wideband technology, holding a total of 5 patents. His work focuses on enhancing signal processing methods, which are crucial for modern communication systems.

Latest Patents

Among his latest patents, Johnson has developed a dual stage automatic gain control system in an ultra wideband receiver. This invention presents a method and apparatus for processing signals in accordance with the Ultra Wideband (UWB) protocol. The system acquires the received signal during a first preamble portion of a data frame associated with the UWB protocol. During this acquisition, a first Automatic Gain Control (AGC) operation is performed to address the noise component of the signal. Following this, a second AGC operation is executed to manage the pulse component of the signal during a second preamble portion.

Another significant patent by Johnson is a circuit and method for dynamically adjusting a filter bandwidth. This invention includes a tracking circuit that controls a locally-generated clock. The receive channel in the tracking circuit receives an incoming signal and a local clock, generating a local signal based on the local clock. It compares the local signal and the incoming signal to produce a data signal and an unfiltered phase error signal. A loop filter then filters the unfiltered phase error signal to provide a filtered phase error signal, which is essential for maintaining signal integrity.
