Latest Patents
Hoo's latest patents include a "System for digitizing and displaying analog signatures" and "Automatic test equipment for integrated circuits." The first patent describes a semiconductor test instrument that provides an AC interrogating signal to an element under test, such as a single pin of an integrated circuit (IC). This system develops horizontal and vertical signals that are applied to a display, producing an analog signature signal representative of the operating condition of the test element. The signals are converted to digital signals and stored in memory for comparison with a reference signal from a known good element.
The second patent outlines an apparatus that produces an analog signature signal relative to a circuit node of an electronic circuit. This signal is generated from horizontal and vertical signals directed to an integrator/A-D converter, which produces a set of four digital signals representing the analog signature. These digital signals are compared against reference values to ensure the integrity of the circuit node.
