Abstract: A switch multiplexer device comprises a plurality of analog switches, and an embedded digital sequencer in operative communication with the analog switches. The embedded digital sequencer including a plurality of sequence control registers. The embedded digital sequencer is configured to transmit control information to the analog switches, with the control information including single or extended control information. The extended control information is employed to pre-load operational information for switch configuration updates when single control operations are conducted. In one embodiment, the switch multiplexer device includes a bitwise manipulator and a data array storage, which are in operative communication with the analog switches and one or more of the sequence control registers.

Abstract: A bonded wafer structure has a device wafer 18 bonded to a handle wafer 10. A capacitor including a bottom plate as the surface 11 of handle wafer 10, a dielectric layer 12 and a top plate 15 is embedded in the bonded structure. A contact trench 22 extends from the surface 8 of device wafer 18 to the top plate 15 of the embedded capacitor.

Abstract: A current generator and method of making a current generator in which two resistors are provided, each in series with one of two transistors in the generator, and in which one of the resistors is trimmed if the reference current is too large and the other is trimmed if the reference current is too small, thereby obviating the problems of the prior art in which one resistor must be trimmed by a potentially large and unacceptable amount. The two resistors are formed with a distribution of resistances which is centered on their corresponding target resistance values so that the number of resistors to be trimmed and the amount of trimming per resistor are reduced. The appropriate target resistances of the resistors can be determined if a maximum trim factor is set. The method is insensitive to variations in the process by which the resistances of the resistors are initially set and reduces the variability of the untrimmed reference current with respect to resistor critical dimensions.
