A two-stage variable gain low noise amplifier (VGLNA) topology is proposed, which adopts a parallel interstage resonance. The characteristics of the parallel inter-stage resonance in gain enhancement are analyzed and this is then followed by the application of a simple circuit consisted of two transistors as the variable gain stage. The VGLNA is designed and simulated based on a 0.18μm CMOS technology for 8-GHz X-band applications. Simulation results show 13.63dB of power gain, 3.60dB of noise figure, 4.27dBm of IIP3 and dc power supply of 1V with 35.67mA current drawn.

A low voltage topology that uses a capacitively coupled resonating element has been introduced using 0.18 mum CMOS technology. The topology utilizes the decoupling scheme to dc isolate circuit elements that are connected in series and share a common dc current. A 5.7 GHz variable-gain low noise amplifier (VGLNA) is presented with simulation results exhibiting a noise figure of 1.02 dB, power gain of 19.41 dB with gain tuning range of 6 dB and IIP3 of -1.11 dBm. The power consumption reported is 12.88 mW at supply of V dd = 0.7 V for power optimization circuit. Simulation results show that the proposed VGLNA has better noise performance and improved power consumption compared to the conventional cascode VGLNA

In this paper, we propose a bidirectional buffer repeater insertion to reduce the RLC tree delay in multi-source multi-sink systems which involve four significant factors in our works. First, inductance effect is taken into account due to the reason that chip sizes with the exponential reduction and high work frequency. Second, bidirectional buffer repeater could improve interconnect delay more than unidirectional buffer insertion. Third, the location of insertion buffer is also considered in our work. Fourth, more than one buffer could be inserted in critical path while buffers have already existed. Finally, we develop a graphical user interface for designers to estimate the delay with bidirectional buffer repeater insertion target multi-source multi-sink systems. Experiment results shown that the reduced delay rate is 50.73% and 64.47% in 0.18 and 0.35 micron fabrication process, respectively

This paper presents a dual band low noise amplifier (LNA) for 1.8 GHz DECT and 2.4 GHz WLAN applications employing positive feedback technique. This LNA exploits a positive feedback capacitor connected to a conventional cascaded inductive source degenerated LNA whereby the connection of a capacitor determines the operating frequency of the LNA. For operation at 1.8 GHz DECT, the capacitor is feedback to both transistors of the cascaded LNA and as for 2.4 GHz WLAN application, the capacitor is feedback to only one of the transistors. Two switches are employed to control the connection of the feedback capacitor to the LNA. By switching the connection of the feedback capacitor, the narrow-band gain and impedance matching are achieved at both 1.8 GHz and 2.4 GHz frequency bands. The LNA has been simulated using 0.18 μm CMOS technology and results attained for both two bands are as followed; gain, S21 = 21 dB, noise figure, NF = 0.8 dB and linearity with third-order intercept point, IIP3 =- 0.13 dBm. Simulation results prove that the technique works and a dual-band LNA with a chip size comparable to a single-band LNA is realized with the proposed topology.

In this paper we analyze the viewer-perceived quality of a compressed video stream, which is transmitted over a lossy IP network with QoS (quality of service) mechanism. We demonstrate that when jointly considering the impact of coding bit rate, packet loss ratio and video characteristics, there is an optimal encoding scheme, which maximizes the viewer-perceived quality. The video content, the compression and the transmission are represented in a vector X of d parameters. Based on the subjective tests, we obtain a set of observation pairs of labeled samples Pi = {Xi ,Qi}, where Qi is the quality class related to the vector of input parameters Xi. We introduce a novel method to predict the optimal encoding scheme based on canonical discriminant analysis (CDA) for feature classification.

Despite of the many advantages of OFDM, it has two main drawbacks which are high peak to average power ratio (PAPR) and synchronization problem. High PAPR causes saturation in power amplifiers, leading to intermodulation products among the sub carriers and disturbing out of band energy. Therefore, it is desirable to reduce the PAPR by means of PAPR reduction schemes. However, it caused the degradation of BER and enhanced the growth of out of band radiation which has led to the degradation of OFDM overall performance. In this paper, OFDM system with an enhanced clipping technique has been proposed, the effects of clipping have been analyzed and the system is evaluated by integrating with its significant features including convolutional forward error control coding, oversampled inverse fast Fourier transform (IFFT) and digital filtering technique in order to minimize the effects of clipping. It is shown that the bit error rate (BER) of the clipped OFDM signal is improved, the PAPR is further reduced and the effect of out of band radiation is minimized. Besides, other effects of the filtering technique are also analyzed in order to optimize the overall performance of our proposed system.

Annual International Conference of the IEEE engineering in Medicine and Biology Society (EMBC)

作者： P. Rolfe Harbin Institute of Technology Harbin China Department of Communication Computer & System Sciences University of Geneva Italy Advanced Research Institute for Science and Engineering Waseda University Tokyo Japan

To meet needs in cell and tissue engineering bioreactors are evolving to allow cells and tissues to be cultured under precisely defined physical and chemical conditions. Many cell-tissue types are now being cultured, and considered in this work are chondrocytes, vascular endothelial cells, and smooth muscle cells. The culture processes are dynamic and optimisation requires monitoring of key process variables. The chemical sensing in cell and tissue bioreactors described here has the long term aim of achieving automatic optimal control. Invasive and non-invasive electrochemical and optical systems are described for a wide range of target analytes (gases, ions, metabolites, hormones and proteins), but emphasis is on O 2 , pH, CO 2 and glucose. The sensing is performed with: (a) interrogation via the bioreactor wall; (b) probes placed within the cell culture chamber; (c) analysis within a shunt/sampling chamber. Analysis of culture medium is used for measurement of glucose and for proteins that are markers of cell biosynthetic behaviour. Optical absorbance and scatter of cells and tissues are also investigated for both chemical and structural analysis

A new detection scheme, namely AND subtraction technique is proposed and presented in this paper. The theory is being elaborated and experimental results have been done by comparing double-weight (DW) code against the existing code, Hadamard. In this paper we have proved that AND subtraction technique gives better bit error rates (BER) performance than Complementary subtraction technique against the received power level.

The extension of telecommunication frontiers towards deep space scenarios has opened new horizons in the way of designing networking infrastructures and has raised the necessity of developping novel communication paradigms, more suited to this specific environment. Under this view, given the hazardous operative conditions (very large latencies and frequent link disconnections), in which the exchange of data has to be performed among remote peers, the exploitation of TCP-based transmission schemes does not offer satisfactory results. On the contrary, the use of erasure coding schemes and more appropriate Automatic Repeat reQuest(ARQ) approaches, available within the Packet Layer Coding-based protocols and the Consultative Committee for Space Data systems (CCSDS) protocol architectures respectively, assure better performance results. In this paper, the adoption of erasure codes within CCSDS protocol stack is considered, and its effectiveness is evaluated with respect to ARQ-based transmission schemes available within the CCSDS File Delivery Protocol and hence proposing a combined use of erasure codes and ARQ schemes in order to optimize the overall performance.
