Latest Patents
One of his latest patents is focused on time measurement in automatic test equipment. This invention includes an apparatus for automatically testing electronic circuits and performing time measurements. It features a time measuring circuit that counts clock pulses between stop and start event edges. The design incorporates two independent input selectors that connect one of several inputs to the time measuring circuit. Additionally, it includes a plurality of local comparators located within the test apparatus, which generate an event edge upon receiving a signal that crosses a threshold value. The patent also discusses making time measurements of signals at digital and analog pins using local comparators connected to input selectors over deskewed transmission paths.
Another significant patent is the differential input selector. This invention allows for the selective connection of one of several differential inputs to a differential output. The selector consists of multiple pairs of differential input lines, a differential output bus, and a separately powerable differential amplifier connected to each pair of input lines. The amplifier can be powered on and off to connect the input lines to the output bus selectively.
