A compact chemiluminescence detector for glucose measurement based on a single planar transparent EWOD (electrowetting-on-dielectrics) device is designed and manufactured. Its sensitivity can be as high as 0.12V/μM, and it has a large detection range from 1μM to 20mM, and a low detection limit of 1μM. Such a detector demonstrates its potential as a portable immuno-detector with prompt response and low cost measurement compared with expensive and bulky traditional instruments.

Adaptive VSS boosting with process variation compensation is proposed to reduce the standby leakage by 6X at room temperature and improves the write static noise margin. The N-pulse read assist circuit enables higher read stability and faster read speed. The systematic BL capacitance variation is detected, and a proper WL voltage is generated to mitigate the BL discharging speed variation by 20%.

This paper proposed a novel single-layer planar design of a microfluidic chip which utilizes inertial forces to realize continuous separating and three-dimensional (3D) focusing of particles. The theories of inertial microfluidics were analyzed and numerical simulation with COMSOL Multi-physics was verified by reported work. The results showed that both 3D focusing and separating of particles with a diameter of 1.0 μm and 9.9μm were obtained by changing the flow rates of inlets. The novel microfluidic design was robust, simple to perform and could easily be manufactured for laboratory and biomedical applications.

Chemical vapor deposited (CVD) graphene is one of the most widely-used methods to get large-area graphene. However, both CVD fabrication process and necessary transfer process will introduce a lot of defects. Therefore, reducing the defects in CVD graphene is a critical problem. In this work, we report the annealing effect to reduce the defects in graphene fabricated by CVD and transferred to Si/SiO 2 substrate. We annealed the CVD samples at five different temperatures in N 2 for 30 s. The Raman spectroscopy shows the defects can be reduced in the range of 200°C to 600°C. Atomic force microscopy (AFM) also indicates a much smoother surface can be reached below 600°C. When the annealing temperature above 800°C, the average carbon-carbon distance increases with the temperature. This will lead to a larger corrugation which is one kind of defects. Thermal expansion generated by high temperature will also damage the graphene lattice structure and therefore produces more disorders.

This paper presents a unified parallel radix-16 turbo decoder asic for 3GPP-LTE and WiMAX systems. A radix-16 decoding for both binary and duo-binary turbo codes is proposed to reduce complexity as well as critical path delay. In addition, the two distinct interleavers in the standards are implemented with low-complexity address generator and barrel shift networks. Furthermore, quad-bank memory partition facilitates parallel radix-16 decoding without address conflict. Fabricated in TSMC 65nm CMOS process, the asic attains 691Mbps throughput running at 512MHz and 5.5 iterations. For the 326.4Mbps LTE peak data rate, it consumes only 193mW at 0.9V supply voltage with unprecedented energy efficiency of 0.108nJ/bit/iteration.

This paper presents a 20Gb/s Limiting Amplifier (LA) with the active interleaving feedback technique both to broaden the bandwidth and achieve flatness response. The LA includes an input match and DC offset cancellation (DCOC), a four-stage 3rd order amplifier core and an output buffer for test. Simulated in the 65nm CMOS technology, the LA exhibits a voltage gain of 38.5dB, a 3-dB bandwidth of 18GHz and an integrated input noise of 0.56mV with the area of only 0.45 × 0.25 mm 2 . The chip excluding buffer is supplied by 1.2V VDD and consumes DC power of 61mW.

In this paper, we propose a hybrid router which combines circuit switching and packet switching with virtual channels for on-chip networks in order to efficiently transfer streaming and best-effort traffics in specific applications. Time Division Multiplexing (TDM) technique and clock-gating scheme are used to take the benefits from the flexibility and throughput advantage of packet-switched router and superior power efficiency performance of circuit-switching. Synthesis and simulation results show that the proposed router has a gain of optimization in latency and average power consumption compared to either of the routers with single switching technique, with a slight growth of 6.8% in area overhead, while the virtual channels increase the network bandwidth by 26%.

This paper presents an implementation of H.264 decoder on a 24-core processor. H.264 provides many new features that require complex computations compared to the previous video coding standards, thus introduces great challenges to implement it efficiently. Multiprocessor emerges as a good solution because it provides high parallelism rather than high clock frequency to improve the system performance energy efficiently. By utilizing hardware accelerators and different levels of parallelism mechanism including function-level parallelism, data-level parallelism and thread-level parallelism, our proposed H.264 decoder shows a throughput of 58fps@720p at 800MHz with 780mW power dissipation.
