摘要： A high frequency push-push oscillator is disclosed. The high frequency push-push oscillator includes a resonant circuit, including tank transmission lines or an inductor capacitor (LC) tank circuit, for generating a differential signal having a resonant frequency, and a Gm-core circuit for converting the differential signal to an output signal having an output frequency that is higher than the resonant frequency. The Gm-core circuit includes cross-coupled first and second transistors having first and second gates, drains, and sources, respectively, and first and second gate transmission lines. The first and second drains are in electrical communication with the resonant circuit. The first gate transmission line is joined with the first gate and the resonant circuit and the second gate transmission line is joined with the second gate and the resonant circuit. The Gm-core circuit includes a differential transmission line positioned between the first and second gates of the first and second transistors.

摘要： Methods and devices including a light display transceiver device are disclosed. Disclosed methods and devices include a light source array including at least one pixel unit, the at least one pixel unit including one of a single pixel, a plurality of groups of cooperating single pixels, a combination of singles pixels and groups of cooperating single pixels, and a single group of cooperating single pixels. Control wires are joined with each of the at least one pixel units. A controller is joined with the control wires for controlling each of the at least one pixel unit. The light source array is configured to operate in at least one of three modes, a full-space-division-duplex (FSDD) mode, a half-space-division-duplex (HSDD) mode, and a time-division-duplex (TDD) mode. The controller causes the light source array to operate in one of the three modes.

摘要： A cross-connect switch architecture is described. A cross-connect switch device includes a cross-point switch array, a plurality of photo detectors and a plurality of amplifiers. The cross-point switch array includes a plurality of switches. Each switch is coupled between a respective photo detector and a respective amplifier and is configured to couple the respective photo detector to the respective amplifier when the switch is selected.
