The first capacitor has a first terminal electrically coupled to the gate terminal of the power transistor. The first switch is arranged between a second terminal of the first capacitor and a first predetermined voltage. The measurement circuit is used to measure a differential voltage across the first capacitor. The gate drive circuit is configured to pre-charge the first capacitor to obtain a second predetermined voltage across the first capacitor. The gate drive circuit is further configured to arrange the first switch in an on state to turn on the power transistor and to electrically couple the first predetermined voltage to the second terminal of the first capacitor. The first capacitor is initially pre-charged at the second predetermined voltage. | 2016-05-26 |
20160149516 | LAUNCH CONTROL OF MOVABLE LAYER IN ELECTROMECHANICAL DEVICES - This disclosure provides systems, methods and apparatus for forming electromechanical devices having a gap between a movable layer and a fixed layer. In one aspect, the movable layer may be supported by hinge structures, and the design of the hinge structure may be controlled to provide a desired amount of flexure, providing electromechanical devices with a desired gap height. The height of the gap may be larger than the thickness a sacrificial material used during the fabrication process. In another aspect, the design of the hinge structure may be used to control threshold voltages of electromechanical devices. | 2016-05-26 |
