A semiconductor device includes at least a first transistor including at least a second level metal layer (second metal layer) above a first level metal layer coupled by a source contact to a source region doped with a first dopant type. The second level metal layer is coupled by a drain contact to a drain region doped with the first dopant type. A gate stack is between the source region and drain region having the second level metal layer coupled by a contact thereto. The second level metal layer is coupled by a contact to a first isolation region doped with the second dopant type. The source region and drain region are within the first isolation region. A second isolation region doped with the first dopant type encloses the first isolation region, and is not coupled to the second level metal layer so that it electrically floats.

Transistor having double isolation with one floating isolation

A light driving system is provided that includes a light dimmer that receives an AC input signal and provides a dimmer output signal that includes a fast rising leading edge, a rectifier that receives the dimmer output signal and provide a rectified dimmer output signal and an AC/DC converter that filters the rectified dimmer output signal to provide a DC input signal that is employed to drive a light. The light driving system also comprises a protection circuit that limits current to the AC/DC converter during the fast rising leading edge of the dimmer output signal.

Light driving system and method

A system includes control circuitry configured to provide one or more control pulses in response to a command signal, the one or more control pulses being communicated from the control circuitry to associated circuitry via a connection. A detector is configured to detect a disturbing signal that mitigates reception of the one or more control pulses via the connection. The command signal is controlled to cause the control circuitry to provide one or more additional control pulses when the disturbing signal is detected by the detector to improve a likelihood of the reception of the one or more control pulses via the connection.
