Title: Dennis C. Stone: Innovator in Amplifier Technology
Introduction
Dennis C. Stone is a notable inventor based in Glendale, CA, who has made significant contributions to the field of amplifier technology. With a total of 3 patents to his name, he has developed innovative methods that enhance the performance of variable gain amplifiers.
Latest Patents
One of his latest patents is titled "Amplifier gain control method using conditional updating." This invention involves a peak detection system that utilizes a variable gain amplifier (VGA). In this system, a counter is initialized, and a countdown is triggered. Each time a qualified peak is detected, the counter is re-initialized. If the countdown is completed, the VGA gain is updated. This method effectively boosts amplifier gain that is too low to generate a qualifying threshold, while also overlooking short periods of very low output.
Another significant patent is the "Method and apparatus for a digital peak detection system including a." This digital peak detection system digitizes analog signals and provides absolute values to a series of one-cycle delays and a sequence of comparator stages. Each digital sample is compared in parallel to a number of preceding samples equal to the number of active comparator stages. Control signals activate these comparator stages to determine the sample comparison window length, optimizing peak detection using a variable gain amplifier. The gain is updated based on the amplitude difference between actual and desired peak samples, ensuring efficient performance even when sample amplitudes are smaller than a qualifier threshold.
