摘要： A semiconductor light emitting device, such as the light emitting diode (LED) or the laser diode (LD), having a structure in which a light emitting area is a double heterostructure or a multi-layer quantum well structure. The light emitting area is formed on a substrate. Subsequently, an electrically conductive oxide layer as a transparent window layer to eliminate the crowding effect is formed on the light emitting area. The substrate layer consists of a GaAs substrate and a GaAsP layer to increasing the band gap energy of the substrate. The electrically conductive oxide layer is formed of AlZnO(x) material, having a lower electrical resistivity and a high transparency in the visible wavelength region. The window layer is formed using a physical vapor deposition or a metalorganic chemical vapor deposition.

摘要： An apparatus for amplifying differential signals is provided. The apparatus comprises a differential amplifier, a first impedance component, a second impedance component, a voltage source and a high-pass filter. The differential amplifier receives an input differential signal with a first terminal and a second terminal. The differential amplifier also drains currents from the voltage source into a third terminal and a fourth terminal via the first and the second impedance components respectively. The high-pass filter receives the input differential signal and outputs a control differential signal to control the first and the second impedance components so that the impedance of the first and the second impedance components vary inversely in response to the voltages at the first and the second terminals respectively when the state of the input differential signal changes.
