Abstract: Provided is a preparation method of a detector material. The present disclosure epitaxially grows a buffer layer on a surface of a gallium arsenide substrate, deposits a silicon dioxide layer on the buffer layer, and etches the silicon dioxide layer on the buffer layer according to a strip pattern by photolithography and etching to form strip growth regions with continuous changes in width. Finally, a molecular beam epitaxy (MBE) technology is used to epitaxially grow the detector material in the strip growth regions under set epitaxy growth conditions. Because of the same mobility of atoms arriving at the surface of the substrate, numbers of atoms migrating to the strip growth regions are different due to different widths of the strip growth regions, such that compositions of the material change with the widths of the strip growth regions or a layer thickness changes with the widths of the strip growth regions.

Abstract: An On-Off Shift Keying (OOK) receiver has non-continuous Automatic Gain Control (AGC) that sets gain at the beginning of each frame and locks the gain setting for the remainder of the frame, preventing OOK data from causing AGC loop instability. An AGC controller initializes to maximum the gain settings for a Low-Noise Amplifier (LNA), Low-Pass Filter (LPF), and a Programmable Gain Amplifier (PGA) in series that power a rectifier generating a voltage output to a 1/0 data decision circuit. A level detector compares the voltage output to two thresholds. When both thresholds are exceeded, the AGC controller steps down gain settings until the voltage output is between the two thresholds, when the gain settings are locked for the remainder of the current frame. A frame detector resets the AGC controller between frames when a long series of 0 data between frames is detected. LNA gain is reduced last.

Abstract: Methods and apparatus for adaptive termination calibration of high-speed links. The methods provide a novel termination calibration obtained in conjunction with link training without using an external reference under which the termination resistors for transmitters (Rtx) and receivers (Rrx) are calibrated to the real channel impedance as part of the link training. The techniques may be implemented to optimize high-speed link operation in terms of impedance match between a channel's characteristic impedance and the source termination of a transmitter and the receiver termination of a receiver. During link training, both Rtx and Rrx are adjusted to maximize a peak amplitude of a received signal. Under one approach for bi-directional links, the Rrx for the receivers at both ends of the link are calibrated substantially concurrently. Under another approach, a calibrated Rrx for a first receiver is used for calibrating the Rrx for the second receiver.
