Aiming at the problems of using optocouplers to achieve logic level matching in current communication circuit, there are many components, high cost, and requirements for component parameters. Based on basic circuit matching, this paper combines The research principle triode switch, Schottky diode’s unidirectional conduction low voltage drop characteristics, introduces a inter-module with switch...

the error of inertial navigation systems increase versus time, therefore for achieving higher accuracy specially in long time navigations we have to use an aiding system. global positioning system is the best aiding system in this case. in this paper we first simulate a gps and ins; then simulate tightly integration and finally review adaptation method of kalman filtering a fuzzy adaptive kalma...

As for the cell-to-cell inconsistency of packing lithium-ion batteries, accurate equivalent modeling plays a significant role in working characteristic monitoring and improving safety protection quality under complex conditions. In this work, novel covariance matching–electrical circuit method is proposed to realize adaptive state characterization by considering internal reaction features, an i...

In this paper, a new voltage controlled first order all-pass filter is presented. The proposed circuit employs a single differential voltage dual-X second generation current conveyor (DV-DXCCII) and a grounded capacitor only. The proposed all-pass filter provides both inverting and non inverting voltage-mode outputs from the same configuration simultaneously without any matching condition. Non-...

in this paper, a neural network model reference adaptive system speed observer is designed, which can be used in speed control of linear induction motors (lims). dynamical equations of lim have been considered accurate. in other words, the end effect and the electrical losses of the motor have been included in the motor equivalent circuit. then equations of the reference model and adaptive mode...

Abstract This paper describes the design of Low Noise Amplifier (LNA) circuits with different types of matching circuits at the input side and output side at 6 GHz. This paper compares the results of all possible combinations of ‘T’ and ‘L’ type matching circuits. The designed circuit is simulated with Advanced Design System (ADS) software. Each circuit is simulated for, with and without stabil...

Consider a directed graph G in which every edge has an associated real-valued distance and a real-valued weight. The weight of an undirected circuit of G is the sum of the weights of the edges, whereas the distance of an undirected circuit is the sum of the distances of the forward edges of the circuit minus the sum of the distances of the backward edges. A trivial circuit is a two-edge circuit...

This paper presents a new cost-efficient realization scheme of pattern matching circuits in FPGA structures with embedded memory blocks (EMB). The general idea behind the proposed method is to implement combinational circuits using a net of finite state machines (FSM) instead. The application of functional decomposition method reduces the utilization of resources by implementing FSMs using both...

in the current iris recognition systems, noise removing step is only used to detect noisy parts of the iris region and features extracted from there will be excluded in matching step. whereas depending on the filter structure used in feature extraction, the noisy parts may influence relevant features. to the best of our knowledge, the effect of noise factors on feature extraction has not been c...

In this article a novel charge pump circuit is introduced. The proposed circuit utilizes a bulk driven cascode current mirror through an adaptive gate bias technique, that results in a high output impedance over a very wide output voltage range, accurate Charge/ Discharge current matching, which minimizes the steady-state phase error in a phase-locked loop (PLL), and low transient glitches. The...
