Publication number: 20240087828Abstract: Microelectromechanical systems (MEMS) switches are disclosed. Parallel configurations of back-to-back MEMS switches are disclosed in some embodiments. An isolation connection of constant electrical potential may be made to a midpoint of the back-to-back switches. In some embodiments, a separate MEMS switch is provided as a shunt switch for the main MEMS switch. MEMS switch device configurations having multiple switchable signal paths each coupling a common input electrode to a respective output electrode are also disclosed. The MEMS switch device includes shunt switches each coupling a respective output electrode to a reference potential. The presence of a shunt switch coupled to an output electrode enhances the isolation of the signal path corresponding to that output electrode when the path is open.Type: ApplicationFiled: November 17, 2023Publication date: March 14, 2024Applicant: Analog Devices International Unlimited CompanyInventors: Padraig Fitzgerald, Philip James Brennan, Jiawen Bai, Michael James Twohig, Bernard Patrick Stenson, Raymond C.

Patent number: 11228310Abstract: Optically isolated micromachined (MEMS) switches and related methods are described. The optically isolated MEMS switches described herein may be used to provide isolation between electronic devices. For example, the optically isolated MEMS switches of the types described herein can enable the use of separate grounds between the receiving electronic device and the control circuitry. Isolation of high-voltage signals and high-voltage power supplies can be achieved by using an optical isolator and a MEMS switch, where the optical isolator controls the state of the MEMS switch. In some embodiments, utilizing optical isolators to provide high voltages, the need for electric high-voltage sources such as high-voltage power supplies and charge pumps may be removed, thus removing the cause of potential damage to the receiving electronic device. In one example, the optical isolator and the MEMS switch may be co-packaged on the same substrate.Type: GrantFiled: October 26, 2020Date of Patent: January 18, 2022Assignee: Analog Devices Global Unlimited CompanyInventors: Ying Zhao, Alan O'Donnell, Michael James Twohig, Olly J.

Patent number: 9583294Abstract: A MEMS switch has a base formed from a substrate with a top surface and an insulator layer formed on at least a portion of the top surface. Bonding material secures a cap to the base to form an interior chamber. The cap effectively forms an exterior region of the base that is exterior to the interior chamber. The MEMS switch also has a movable member (in the interior chamber) having a member contact portion, an internal contact (also in the interior chamber), and an exterior contact at the exterior region of the base. The contact portion of the movable member is configured to alternatively contact the interior contact. A conductor at least partially within the insulator layer electrically connects the interior contact and the exterior contact. The conductor is spaced from and electrically isolated from the bonding material securing the cap to the base.Type: GrantFiled: May 15, 2014Date of Patent: February 28, 2017Assignee: Analog Devices GlobalInventors: Check F.

Patent number: 8124436Abstract: A MEMS switch with a platinum-series contact is capped through a process that also passivates the contact by controlling, over time, the amount of oxygen in the environment, pressures and temperatures. Some embodiments passivate a contact in an oxygenated atmosphere at a first temperature and pressure, before hermetically sealing the cap at a higher temperature and pressure. Some embodiments hermetically seal the cap at a temperature below which passivating dioxides will form, thus trapping oxygen within the volume defined by the cap, and later passivate the contact with the trapped oxygen at a higher temperature.Type: GrantFiled: May 27, 2011Date of Patent: February 28, 2012Assignee: Analog Devices, Inc.Inventors: Mark Schirmer, Raymond Goggin, Padraig Fitzgerald, David Rohan, Jo-ey Wong
