A closed loop switch control system and a corresponding method is provided for controlling an impedance of a switch. The switch, which usually comprises a transistor switch, may be part of an external circuit. The system comprises the switch and a control unit coupled to the switch. The control unit is configured to regulate an impedance of the switch to a reference impedance while also enabling a fast switch response time. This is achieved by configuring the control unit to have a frequency response comprising a plurality of dominant poles and at least one zero.

Closed loop switch control system and method

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.
