This paper presents a 2.4GHz fully integrated power amplifier based on 0.18μm SiGe BiCMOS technology for wireless local area network applications [1]. The power amplifier shows a 1 dB compression output power of 22.19dBm at an input power of 0.135dBm. A temperature-insensitive bias circuit is used in this PA design to improve the amplifier linearity. The total fabricated die size is about 1.5mm×1.2mm. The designed PA based on SiGe BiCMOS technology demonstrates a competitive linearity performance compared with GaAs, when considering the factors of cost and process complexity.

Human-computer interaction (HCI) has great potential for applications in many fields. A HCI method has been developed based on audio-visual perceptive features and dynamic interactive pooling. A mode analysis based fusion strategy is proposed to fuse the interactive responses from audio-visual modalities especially for the case there are deviations from the modalities at the same time. The developed approach can be applied with a better performance even in single modal with multiple interactive users in the scenario. The users in the scenario are endowed with a fair chance to perform HCI by their interactive priorities no matter how many modalities used, and the interactive authority and priority are updated dynamically according to the variation of HCI content. The scenario and multiple users altogether are regarded as a dynamic HCI pooling. The diversity of interactive habits among multiple users is considered in an ordinary hardware from a crowded scene without any hypothesis for the scenario contents in advance. The pooling is updated dynamically to meet the user demands with the most intentions preferentially. Comparative study with state-of-the-arts has indicated the superior performance of the proposed method. © 2015 SERSC.

The paper first argues the system level design of the OLED drive chip. After analyzing the the feature of OLED and the display pane[1] , it presents the process to eliminate the cross talk effect by the precharge circuit, and compares the drive efficiency between two precharge schemes, then proposes the dual radix interleaving clock architecture to enhance the lighting efficiency and dynamic feature of the OLED display panel. The circuit is realized by the Dual State Machine Locks. At last it demonstrates the effect on the efficiency of both display and transmission among three RAM management architecture, which is to enable the OLED drive chip to be adapt to different gray scales.

This paper proposes a time grayscale control method associated with source current mirror using binary latch scheme to take place conventional structure which uses capacitance with MOSFET. The time grayscale control method based on the characteristics that the Luminance can "stay for a while" in human eyes controls the time period of pixel work to make different gray scales, and it solves the division limitation of magnitude control. The data we used has 2 states, high or low, just make the OLED on or off. In the pixel select period, the data is locked in the binary latch, and during the unselect period, the data in the latch will still make the OLED work as the situation just in the select period. Here we use high impedance , high precise constant current source mirror structure to drive the OLED, which can solve the problems including delay of the capacitance and nonuniform over display in the drive circuit of AM-OLED in existence.

This paper presents the design and implementation of FPD system based on the fractal scanning IP core. The system is made up of the multimedia video card, the Ethernet video transmitter unit, the fractal scanning controller and the LED flat panel display. Using the fast Ethernet agreement technique to substitute the traditional difference data transfer method obtained the advantages such as fast speed, long distance data transmission and the high reliability of transceiving data. The novel control mode that the fractal scanning IP core described with Verilog language is embedded in the FPGA hardware frame can efficiently increase the imaging gray scales, and speed up frame frequency of display system. Serial applications and tests indicate that there is no need to using high-speed IC circuits to realize the high articulation and resolution display of video image with the proposed method.

Multi-view video coding (MVC) is one of the newest video compression standards, which has better compression efficiency than single view video coding. As the coding scheme exploits spatial, temporal and inter-view dependability for this scope, it leads the reconstructed multi-view video (MVV) become worse when transmitted in error-prone networks. To solve this problem, an effective error concealment (EC) method for MVC is proposed in this paper. The proposed method conceals a corrupted block by combining a few candidate blocks in intra-view reference frames or inter-view reference frames. The experimental results show that the proposed method has better concealment effect if using the inter-view reference frames effectively in B-view. © 2011 IEEE.
