Abstract: Image projection utilizing light-emitting diodes on a silicon (LEDoS) substrate is described herein. LEDoS devices selectively activate LED pixels to produce light. Light can excite color conversion materials of the LEDoS devices to form color images. Images can be projected onto a projection surface.

Abstract: A system to test integrated circuits on a wafer may include a transceiver formed on the wafer. The system may also include an antenna system couplable to the transceiver. The transceiver may be formed in one of a scribe line on the wafer, a chip on the wafer or on an usable portion of the wafer. The antenna system may be formed in at least one of the same scribe line as the transceiver or in at least one other scribe line formed in the wafer. Alternatively, the antenna system may include an antenna external to the wafer.

Abstract: Method and apparatus for adjusting an impedance of a substrate of a Metal-Oxide-Semiconductor (MOS) transistor by providing a bias voltage and connecting a frequency-selective circuit between the substrate and the bias voltage. The frequency-selective circuit is also provided with at least one reactive element, such as an inductive element or a capacitive element, to obtain a certain frequency-response of the frequency-selective circuit and thus adjusts the substrate impedance of the MOS transistor. The method and apparatus are compatible with standard CMOS technology and applicable to RF switches, including T/R switches for processing high-frequency analog signals.

Abstract: The present invention provides a synthesizer having an efficient lock detect signal generator, an extended range VCO that can operate within any one of a plurality of adjacent characteristic curves defined by a plurality of adjacent regions, and a divide circuit implemented using only a single counter along with a decoder. This allows for a method of operating the synthesizer, methods of establishing or reestablishing a lock condition using the extended range VCO, and a method of designing a plurality of divide circuits which each use the same single counter and each use a different decoder.
