The standard steps of P− implantation and silicide block in the complementary metal-oxide semiconductor (CMOS) process are used in this design to implement the proposed diode string. The novel diode string realized by the diodes of P+ with N-well (P+/NW) and P− with N+ (P−/N+) is proposed in this letter. Besides, two diodes are merged together to form a silicon-controlled rectifier path to reduce...
The electrostatic discharge (ESD) immunity test for EMC was one important reliability regulation. The turn-on-efficient on-chip ESD protection circuit is required to clamp the overstress voltage. A new design of ESD protection diodes with embedded silicon-controlled rectifier (SCR) was proposed to protect the gigahertz differential low-noise amplifier (LNA). Experimental results had shown that the...
Transmission loss is the major killer to quality delivery of video streaming, in particular in error-prone environments such as wireless channels. Moreover, indefinite packet delay/jitter can also induce effective loss of received packets at the receiver end due to real-time requirements by the play-out buffer. To address the real-time issue, we propose a novel cross-layer design called PN_DVFI+DPM,...
Multiple reference frame prediction (MRFP) is a new function adopted by H.264. This article studies the impact of MRFP to importance and prioritization of video frames. MRFP allows the use of long-term-memory reference frames and multiple-hypotheses signals for motion prediction and compensation, and can thus greatly change the error propagation behaviors of a lost video frame and reorder its importance...
The FIFO characteristic of the access category queue (AC_VI) reserved for video in the 802.11e MAC limits its performance for high quality video transmission during traffic congestions. To enhance video transmission quality, further service differentiation among the video packets is preferred. To achieve this, this paper presents a novel cross-layer design by proposing a dispersive video frame importance...
