This paper proves that voice over Internet protocol (IP) technology can be combined with satellite transmission in air traffic control (ATC) applications provided that the systems used to implement this approach have been meticulously designed to meet the end-to-end delay requirements and to certify the quality of service they offer under strenuous conditions.We propose a modified E-model and prove...
In this paper, a detailed analysis of the voltage transfer characteristics of vertical nanowire transistor-based CMOS inverter is presented. We show that noise margins are strongly dependent on the source/drain series resistance, and that the extension lengths can be used as tuning parameters to control the noise margin and gains of the inverter.
Vision systems provide a large functional spectrum for perception applications and, in recent years, they have demonstrated to be essential in the development of Advanced Driver Assistance Systems (ADAS) and Autonomous Vehicles. In this context, this paper presents an on-road objects detection approach improved by our previous work in defining the traffic area and new strategy in obstacle extraction...
This paper presents a temperature and supply compensated sub-threshold voltage reference generator which generates a reference voltage of 173 mV at supply voltage of 0.6 V and temperature @ 27 °C, has been designed in 45 nm CMOS technology. Variation of output voltage with temperature over a range of −25 to 85 °C is 172.88 to 173.25 mV which gives temperature coefficient of 19 ppm/°C at supply voltage...
In this paper we present an 8T footless storage element, the FFDICE (FinFET DICE), a dual interlocked structure using Independent Gate SOI FinFET transistors that exhibits soft error resilience characteristics. Compared to the conventional DICE cell, the proposed design achieves area savings by dispensing with the four NMOS driver transistors, retains the excellent tolerance characteristics to single...
This paper presents a new method for sizing the transistors in CMOS gates as an enabling technique for green technology. The technique utilizes an efficient feedback-based system to optimize the transistors sizes in the gates with the fanins of 2 or more. The optimized NAND2-4 gates provide nearly 65% savings in power dissipation and 58% reduction in energy consumption, as compared to their normal,...
This paper concerns the design and the implementation of a transimpedance amplifier (TIA) dedicated to detector of Near Infrared spectroscopy (NIRS). To reduce the effect of the input capacitance on the bandwidth, a bias circuit with low input impedance is connected to input stage. A single ended common source common gate input stage based on a cascode structure is used to get a higher gain bandwidth...
Besides the regular biological or biomedical imaging applications, time-gated fluorescence lifetime imaging microscopy (FLIM) could be used to image living cells or rapid biochemistry reactions by its advantage of wide field and obvious parallel acquisition speed. As the basis of system detection mode, a good fitting algorithm could satisfy the lifetime precision and acquisition demand at the same...
In order to minimize the impact of on-chip Ldi/dt noise on power and performance, Oracle's SPARC M6 processor features an Asymmetric Frequency Locked Loop (AFLL) that dynamically adjusts chip frequency. It achieves 15% improved noise immunity by reacting to the voltage noise asymmetrically through the use of a pair of DCO's that accurately track the response of critical paths. The AFLL is implemented...
In this paper, a highly linear, inductively degenerated, common source narrowband LNA is presented. An extremely simple feed-forward distortion circuit (FDC) which consists of an appropriately sized ac-coupled diode connected NMOS is proposed. This circuit generates distortion components at output, when added at the input node as a feed forward element (M6). These distortion components partially cancel...
The present work deals with experimental analysis and discussion of the light sensitivity of GaAs pseudomorphic HEMT's to visible laser exposure from the viewpoint of microwave noise performance. A comparative study has been performed with respect to the layout of different devices having the same total gate width but different access layouts in terms of gate fingers and pitch. Significant differential...
Noises and variations are ubiquitous, but are ill-understood and in most cases analyzed simplistically, leading to substantial overdesign costs. A novel reliability-centric design method based on unconventionally sizing transistors has been suggested lately. In this paper our aim is to design, simulate, and compare the benefits of unconventional sizing when applied to SRAM bit-cells. The unconventionally...
We address the problem of endowing a robot with the capability to learn a repertoire of actions using as little prior knowledge as possible. Taking a handwriting task as an example, we apply the deep learning paradigm to build a network which uses a high-level representation of digits to generate sequences of commands, directly fed to a low-level control loop. Discrete variables are used to discriminate...
A novel architecture for a bandgap voltage reference is presented in this paper. The voltage reference, designed for image sensor applications, is primarily targeted for a low-noise operation along with other practical constraints such as high power supply rejection, temperature immunity and short start-up time. The analysis and operation of the circuit is discussed and the trade-offs involved in...

The other domino logic circuits used to discriminate the result of proposed circuit are footed domino logic circuit, footless domino logic...
This paper means to explore the application of input-output feedback linearization method to control the model-based firing behavior. The Pinsky-Rinzel (PR) model is used to develop the feedback controller. The epileptiform behavior is modeled by the high frequency burst of 29 Hz and the normal desired behavior is modeled by the periodic firing of 6 Hz. The epilepsy treatment is formulated as a classic...

Compared to a conventional gate drive circuit, the proposed gate driver has capability of reducing the switching losses and switching time without increasing switching noise...
Impact of donor-layer doping concentration and temperature variation on the various noise coefficients and minimum noise figure is investigated for separate gate InAlAs/InGaAs DG-HEMT, in this paper. The noise coefficients, which include the drain noise coefficient (P), gate noise coefficient (R), the correlation coefficient (C) and the minimum noise figure have been evaluated using Pucel's charge...
Domino dynamic circuits are widely used in critical parts of high performance systems. In this paper we show that in addition to the functional limitation associated to the non-inverting behavior of domino gates, there are also performance disadvantages when compared to inverting dynamic gates, which can be related to this feature. These penalties rise from the fact that in order to produce a logic...

This model represents an excitable system with driven noise, which could be associated with diverse processes, from the kinetic...
