摘要： A bidirectional communications interface is provided that connects a transmitter and a receiver, or a transceiver, to a transmission line. Under an embodiment, the bidirectional interface generates positive and negative polarity data signals using two separate differential amplifiers that receive differential signal pairs from each side of a differential link to the transmission line and the transmitter. The bidirectional interface controls common mode rejection in each of the separate differential amplifiers using bias signals generated in response to an output common mode feedback voltage from each of the differential amplifiers. An output amplifier combines the positive and negative polarity data signals to form single-ended output logic signals. The output logic signals represent data received on the transmission line, and are provided to the receiver.

摘要： A scheme for reducing jitter in high-speed digital communication by adaptively controlling the loop bandwidth of a receiver PLL to reduce the relative jitter between the recovered data and clock. The scheme uses phase pointer activity to represent the relative jitter. The phase pointer activity is measured and used to control the receiver PLL loop bandwidth. The receiver PLL loop bandwidth is repeatedly incremented or decremented by a step size based on the comparison between a newly measured activity value and the old activity value, until the phase pointer activity reaches a minimum. Because the PLL performance requirement of the transmitter can be relaxed, compatibility with legacy transmitters and multi-vendor transmitters is enhanced. Because tight control of fabrication process parameters of PLLs may be relaxed, the fabrication yield may also be improved.

摘要： A thin film transistor (TFT) using an oxide semiconductor as an active layer, a method of manufacturing the TFT, and a flat panel display device having the TFT include source and drain electrodes formed on a substrate; an active layer formed of an oxide semiconductor disposed on the source and drain electrodes; a gate electrode; and an interfacial stability layer formed on at least one of top and bottom surfaces of the active layer. In the TFT, the interfacial stability layer is formed of an oxide having a band gap of 3.0 to 8.0 eV. Since the interfacial stability layer has the same characteristics as a gate insulating layer and a passivation layer, chemically high interface stability is maintained. Since the interfacial stability layer has a band gap equal to or greater than that of the active layer, charge trapping is physically prevented.

摘要： A thin film transistor using an oxide semiconductor as an active layer, and its method of manufacture. The thin film transistor includes: a substrate; an active layer formed of an oxide semiconductor; a gate insulating layer formed of a dielectric on the active layer, the dielectric having an etching selectivity of 20 to 100:1 with respect to the oxide semiconductor; a gate electrode formed on the gate insulating layer; an insulating layer formed on the substrate including the gate electrode and having contact holes to expose the active layer; and source and drain electrodes connected to the active layer through the contact holes. Since the source and drain electrodes are not overlapped with the gate electrode, parasitic capacitance between the source and drain electrodes and the gate electrode is minimized. Since the gate insulating layer is formed of dielectric having a high etching selectivity with respect to oxide semiconductor, the active layer is not deteriorated.
