  • Publication number: 20240337686
    Abstract: The techniques and circuits, described herein, include solutions for error compensation in source measurement units (SMUs). An example SMU is capable of both sourcing current to a device under test (DUT) and measuring current through the DUT. An SMU may include a sensing resistor coupled in series with the DUT. A voltage across the sensing resistor may be measured by a current sensing amplifier in order to determine the output current through the DUT. In practice, the resistance of the sensing resistor may vary depending on manufacturing tolerances, etc. A gain of the current sensing amplifier may be calibrated in order to compensate for sensing resistor variance, which increases the accuracy with which current to the DUT can be sourced and measured.

  • Patent number: 10288558
    Abstract: Unique gas cell constructions based on a hollow-core photonic crystal fiber are used, for example, inside a fiber ring laser cavity as an intracavity gas cell. In one embodiment, two simple terminal blocks are coupled to opposite ends of the hollow-core photonic crystal fiber. Each block features a main through-bore with an optical window at one end and an optical fiber chuck fitted at the other end, while a transverse bore intersects the main bore and features a gas fitting for connection to a gas source or vacuum pump. In another embodiment, the hollow-core photonic crystal fiber is contained within an enclosure whose exterior walls are fitted with optical windows and gas ports. Inside the enclosure, fiber clamps supports the ends of the hollow-core photonic crystal fiber at positions adjacent to an in alignment with the optical windows.
