Power supply noise is a critical issue in transition and delay testing. As compared to functional operations, test vectors induce increased switching. This escalation in switching contributes to an increase in power supply noise which, in turn, causes an increase in path delays. During testing, false positives due to excessive noise-induced failures negatively impacts yield. In our previous work,...
In this paper, a new multitarget tracking approach is proposed. In the proposed approach, a non-iterative fuzzy clustering means algorithm is used to generate the association measures between the received measurements and the targets. Measurements-to-tracks associations are computed jointly across all targets and all validated measurements using the non- iterative fuzzy clustering means algorithm...
Improvement in noise performance and Tran conductance using positive feedback approach in bulk driven operational amplifier is proposed in this paper. Downscaling of CMOS technology has compelled the supply voltage to reduce, which in turn demands the reduction in threshold voltage. To overcome the barrier of threshold, bulk driven technique is a good nonconventional approach because it require no...
In present digital circuits, low power consumption with high packaging density is always needed. The continuous reduction of MOSFET devices channel length causes an undesirable Short Channel Effects on the device parameters rendering large power dissipation. Increased leakage current with technology improvement requires tight control. In delay flip flop the storing of data get restricted due to leakage...
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...

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...
