ALEXANDRIA, Va., Aug. 20 -- United States Patent no. 12,392,825, issued on Aug. 19, was assigned to Analog Devices Inc. (Wilmington, Mass.).
"Configurable pin driver circuit output impedance" was invented by Christopher C. McQuilkin (Hollis, N.H.).
According to the abstract* released by the U.S. Patent & Trademark Office: "A test system can provide a test signal to, or receive a test signal from, a device under test (DUT) via a first signal path. The test system can be configured to present a stable (e.g., 50 ohm) impedance at the DUT interface. In an example, the stable impedance comprises a physical polysilicon resistor in series with an output stage of a driver circuit of the test system. The impedance of the output stage can be a func...
