Latest Patents
Among his latest patents is a groundbreaking invention titled "Circuitry for and system and substrate with circuitry for aligning output signals in massively parallel testers and other electronic devices." This patent focuses on signal alignment circuitry that aligns, or deskews, test signals from a massively parallel tester. The invention utilizes a timing portion of each signal received by a rising edge delay element, a falling edge delay element, and a transition detector, all operating in parallel. The control circuitry independently manages the delay of both the rising and falling edge delay elements. The outputs from these elements are then multiplexed together, with the output selected based on transitions detected by the transition detector. This output is sent to pulse generating circuitry, which produces a pulse at each edge for clocking a data portion of each signal into a DQ flip-flop. The output from this DQ flip-flop is subsequently latched into another DQ flip-flop by a reference clock. The system also includes a method for controlling the rising and falling edges of test signals to ensure proper alignment with other signals.
