Title: The Innovations of Richard J Juhn
Introduction
Richard J Juhn is a notable inventor based in Nashua, NH (US). He has made significant contributions to the field of technology, particularly in the area of integrated circuits and crystal oscillators. With a total of 5 patents to his name, Juhn's work has had a considerable impact on the industry.
Latest Patents
One of Juhn's latest patents is focused on compensating for temperature-dependent hysteresis in a temperature compensated crystal oscillator. This invention addresses the issue of hysteresis, which causes the temperature-dependent frequency characteristic of a crystal oscillator to differ based on whether the temperature is rising or falling. By generating a rising temperature-to-frequency mapping polynomial and a falling temperature-to-frequency mapping polynomial, Juhn's method allows for weighted evaluations based on current and past temperatures. This innovative approach enhances the temperature-based frequency compensation of crystal oscillators.
Another significant patent by Juhn involves a tri-level test mode terminal in a limited terminal environment. This technique increases the functionality of integrated circuit terminals without the need for additional terminals. By utilizing at least one tri-level terminal and a converter circuit, the invention provides a logic level indicative of a test mode in response to a corresponding input level. This advancement effectively reduces false detections of the test mode and minimizes the risk of inadvertently enabling other functional modes of the integrated circuit.
