The bearing device has a support ring positioned around a rotating shaft and a plurality of bearing pads provided between the rotating shaft and the support ring and configured to support the rotating shaft. An MOS device is provided having a body of a first conductivity type and at least one region of a second conductivity type in the body, with a conductive layer over at least part of the body and the region of the second conductivity type and insulated therefrom. The consistency tracking information is propagated through a plurality of streaming operators that process the data streams within the data stream processing engine. The differential amplifier generally has a first input that is coupled to the source of the first DE MOS transistor, a second input that is coupled to the source of the second DE MOS transistor, a first output that is coupled to the gate of the second DE MOS transistor, and a second output that is coupled to the gate of the first DE MOS transistor.
