Title: Innovations by Inventor Marc Spehlmann
Introduction
Marc Spehlmann is an accomplished inventor based in North Reading, MA (US). He has made significant contributions to the field of automatic test equipment (ATE) with a total of 4 patents to his name. His work focuses on enhancing the accuracy and efficiency of signal path measurements.
Latest Patents
One of Marc's latest patents is titled "Measuring a leakage characteristic of a signal path." This invention involves systems that determine the parasitic capacitance of a signal path. The parasitic capacitance is then utilized to ascertain a leakage characteristic of the signal path, such as leakage current or leakage resistance. The capability of ATE channels to accurately force current and measure time intervals at prescribed voltages significantly enhances the accuracy of the force current function. This innovation allows for the measurement of small leakage currents, for instance, on the order of 10 nA or less.
Another notable patent is "Controlling a per-pin measurement unit." This invention describes an example of automatic test equipment that includes a per-pin measurement unit (PPMU), logic configured to execute a state machine to control the PPMU, and memory that is part of or separate from the logic. The control system commands the logic, and in response to a command, the state machine is configured to obtain data based on the output of a measurement by the PPMU. This data can be stored in memory or output to the PPMU at a known interval or synchronized to an event.
