    摘要: An architecture and method are provided for preventing snapdown in a voltage controlled MEMS device having a movable actuator with an actuator electrode coupled to a high voltage power supply (HVPS) through a drive circuit, the movable actuator suspended over a cavity electrode formed on a substrate and coupled to a common backplane supply (VssC). Generally, the circuit includes a number of first diodes coupled between the HVPS and the actuator electrode and/or the cavity electrode to provide a forward-biased path to transfer a positive charge to the HVPS when the accumulated charge exceeds a predetermined threshold. Preferably, the drive circuit further includes second diodes to provide a low impedance path to transfer a positives charge from the actuator electrode and/or the cavity electrode to a substrate ground when the accumulated charge results in or exceeds a predetermined threshold voltage. Other embodiments are also disclosed.

    摘要: The quality and reliability of electro-optical modules can be improved, for instance, through improved testing and burn-in of an electro-optical sub-assembly. Reliability can also be enhanced through better methods of constructing an electro-optical module. By arranging both an electrical interface and an optical interface on a sub-assembly, for instance, testing can be performed on both interfaces in a single testing process. Burning-in an electro-optical sub-assembly can also improve the reliability of the module by identifying defects. A method of forming an electro-optical module can provide improved reliability by testing and/or burning-in an electro-optical sub-assembly before assembling the module.

    摘要: An anchor structure placed in an open field in corner areas of the semiconductor die and along die edges for preventing cracks in the die. In the corner areas, the anchor structure is placed perpendicular to a resultant vector force, which is approximately at a 45.degree. angle to an imaginary horizontal line passing through the die. This perpendicular placement of the anchor structure more uniformly distributes the stresses along the anchor preventing corner cracks in the die. Along the die edges, the anchor structures are placed approximately perpendicular to the resultant vector forces that impinge the die edges.

    摘要: A circuit (100) can include a first section (102) that can provide a designated function within an integrated circuit device that can be altered due to current injection at a node (106). A mirror section (104) can mirror the effects of current injection on one or more devices within first section (102) and generate an output indication INJ_EFF representing such effects. In one very particular arrangement, detection of an injected current can be used to prevent false triggering of a switched electrostatic discharge (ESD) current path.

    摘要: An arrangement for optical communication comprises an optical coupler, an opto-electronic board, and an optical fiber. The optical fiber comprises a first refraction surface, a second refraction surface, and an internal reflector. The first refraction surface has a first finite focal length. The second refraction surface has a second finite focal length. In operation, an optical signal enters the first refraction surface, couples from the first refraction surface to the second refraction surface via the internal reflector, and exits the second refraction surface, where the optical signal defines a light path. The light path optically couples the opto-electronic board to the optical fiber.
