Latest Patents

One of Pearce's latest patents is for an "Analog channel for mixed-signal-VLSI tester." This invention provides a mixed-signal tester architecture and methods that minimize data transfer, offer parallel data post-processing within the analog channels, and allow flexible synchronization. The architecture includes multiple analog channels, each equipped with a source digital signal processor (DSP), digital source sequencer, and various instrumentation for both analog and digital measurements. This design enables efficient processing of the device under test (DUT) response, which is used to define parameters for subsequent test cycles, thereby speeding up the overall testing process.

Another significant patent focuses on "Accurate alignment of clocks in mixed-signal tester." This invention addresses the challenge of aligning asynchronously-generated digital and analog clocks in a mixed-signal test system. By utilizing a variable-frequency digital master clock signal, the analog clock signal is phase-aligned with the master clock signal and the stimulus pattern applied to the DUT. This alignment ensures consistent test results across multiple tests, enhancing the reliability of the testing process.
