Emerging feature dense portable microelectronic devices pose several challenges, including demanding multiple supply voltages from a single miniaturized power-efficient platform. Unfortunately, the power inductors used in magnetic-based switching converters (which are power efficient) are bulky and difficult to integrate. As a result, single-inductor-multiple-output (SIMO) solutions enjoy populari... View full abstract»

This brief presents an adaptive excess loop delay (ELD) compensation technique for continuous-time delta-sigma modulators. This technique utilizes a predictive comparator with adaptive control using the sign least-mean-square algorithm to estimate the compensation coefficients. Contrary to other state-of-the-art compensation methods, the proposed technique is immune to manipulation of the loop fil... View full abstract»

In this brief, we present the design of a fully integrated all-analog wireless reflector/repeater that acts as the relay in a phase-sweeping cooperative diversity scheme. This approach multiplies the coverage of an indoor wireless sensor network by four. Using 0.13-mum CMOS and Vdd = 1 V, the active reflector provides 45-dB gain and satisfies network specifications for a dc power of as ... View full abstract»

Publication Year: 2009, Page(s):629 - 633
Cited by:  Papers (5)
| | PDF (412 KB) | HTML

Accurate analog squarers are required for different signal processing functions, such as amplitude modulation, frequency shifting, signal power estimation, and neural and image processing. Transistor-level analog squarers suffer from limited accuracy, particularly in modern deep-submicrometer technology, where the squared law of the MOS transistor in the saturation region is no longer valid. Based... View full abstract»

This brief presents an improved logical-effort model to account for the slope mismatch between the input and output of a gate. The model has a simple formulation in which only one additional parameter is needed, making the analysis suitable for hand calculations. Using 65- and 90-nm complementary metal-oxide-semiconductor technologies, the model maintains less than 5% error in gate-delay estimatio... View full abstract»

We propose a fast hardware algorithm for division in GF(2m) based on the extended Euclid's algorithm. The algorithm requires only one iteration to perform the operations that correspond to the ones performed in two iterations of previously reported division algorithms. Since the algorithm performs modular reductions in parallel by changing the order of execution of the operations, a circuit... View full abstract»

A novel low-power CMOS synchronous counter whose clock-gating logic is embedded into a carry propagation circuit is proposed. The proposed synchronous counter operates with no redundant transitions and requires fewer transistors, minimizing the switching power consumption and silicon area as compared with conventional CMOS synchronous counters. The proposed synchronous counter consisting of 16 bit... View full abstract»

Mutual information separation (MISEP) is a versatile independent component analysis (ICA) algorithm that can be used to handle linear and nonlinear mixtures. By incorporating the a priori information of mixtures, an extended MISEP method is proposed in this brief to recover the source signals from the post-nonlinear-linear (PNL-L) mixtures. One group of multilayer perceptrons and two... View full abstract»

This brief is concerned with the stability analysis for cellular neural networks with time-varying delays. First, an appropriate Lyapunov-Krasovskii functional is introduced to form some new delay-dependent stability conditions in terms of linear matrix inequalities (LMIs). Quite differently, these stability criteria are derived by using the convex combination property, which equivalently converts... View full abstract»

In this brief, stability and bifurcation in a class of networked dynamical systems are investigated. First, it is shown that, for each member of the family, there is a globally attracting region. Then, the local stability of a particular fixed point (0, 0) is investigated; afterward, it is found that this fixed point is a bifurcation point as a certain system parameter varies. Finally, a family of... View full abstract»

This brief addresses the problem of synchronization of two Lu chaotic systems. As opposed to nonlinear Lyapunov-based controllers, which are designed with the aim of rendering the derivative of a Lyapunov function negative along trajectories of the closed-loop system, control design exploits the natural stability properties of the system. The proof relies not only on basic Lyapunov stability theor... View full abstract»

Bose-Chaudhuri-Hocquenghen (BCH) error-correcting codes are now widely used in communication system and digital technology. The direct linear feedback shifted register (LFSR)-based encoding of a long BCH code suffers from the large fan-out effect of some XOR gates. This makes the LFSR-based encoders of long BCH codes not keep up with the data transmission speed in some applications. The technique ... View full abstract»
