Latest Patents

One of Overhage's latest patents is centered around logic signal extraction. This invention outlines methods for producing logic signal displays for an instrument known as a 'logic oscilloscope'. The process begins with sampling a digital input signal as an analog signal, which produces multi-bit digital samples that represent the amplitude of the input signal over time. These samples are then processed using interpolative techniques to determine when the input signal crosses a hypothetical logic level threshold. The resulting transition times and logic states are utilized to generate various digital displays, including logic timing diagrams and state table displays. Additionally, setup and hold time violations can be measured using this information.

Another significant patent is for an oversampled logic analyzer. This device acquires all data and clock signal inputs asynchronously at high speed, utilizing a digital FISO to produce multiple parallel high-speed data samples within each cycle of an internal system clock. The selection process for storing a single data sample in the acquisition memory involves skew adjustment, clock edge detection, and alignment to a reference location. This innovation allows for the detection of setup and hold violations, enhancing the reliability of the logic analyzer.
