Title: The Innovations of Richard F. Keil
Introduction
Richard F. Keil is a notable inventor based in Jonesville, Vermont, known for his contributions to integrated circuit technology. He holds a total of 3 patents, showcasing his innovative spirit and technical expertise in the field.
Latest Patents
One of his latest patents is the "On-demand process sorting method and apparatus." This invention involves a process sort test circuit and methodology designed to determine the performance characteristics of an integrated circuit (IC) chip. The circuit is integrated on the IC chip itself and features an input for receiving an input signal. It includes a first path that transmits the input signal to a first output, which is sensitive to variations in the manufacturing process of the IC chip. Additionally, there is a second path that transmits the input signal to a second output, which is less sensitive to these variations. A pulse generator device is coupled to both outputs to detect differences in arrival times of the input signal, outputting a sort signal if the difference exceeds a preselected magnitude. This sort signal enables the output indication of the IC chip's performance characteristics.
Another significant patent is the "Flash output LSSD latch." This invention is a two-stage latch or shift register latch that features a reduced propagation delay in the second stage, making it suitable for LSSD type integrated circuits. The first stage receives and latches data, and it may also include a scan input for testing data. The data is then passed to a second stage, which provides the output and latches it. The preferred second stage includes cross-coupled inverters and a complementary clock stage that selectively passes the received data from the first stage to the output.
