The concept of mechanical impedance represents the interactive relationship between deformation kinematics and the resulting dynamics in human joints or limbs. A major component of impedance, stiffness, is defined as the ratio between the force change to the displacement change and is strongly related to muscle activation. The set of impedance components, including effective mass, inertia, damp...
This paper presents 10-bit, 1.5 MS/s, 2.5V, Low Power Pipeline analog to digital converter using capacitor coupling techniques. A capacitance coupling foldedcascode amplifier effectively saves the power consumption of gain stages of ADC in a 0.25 μm CMOS technology. The ADC also achieves Low power Consumption by the sharing an op-amp between two successive pipeline stage further reduction of po...
A new dynamic comparator is presented using modified gain stage followed by latch stage for high speed analog-to-digital converter. The gain stage of proposed comparator is a modified class AB pre-amplifier which makes it suitable for high speed of operation with small delay time and low power. The circuit is simulated in 180 nm process technology using tool Cadence Virtuoso with a supply volta...

Geometric modelling and structure analysis of converter tilting device by using Pro/E program .The design Principle, basic design structure were ...
Flash Analog to Digital Convertor (FADC) is frequently used in nuclear and particle physics experiments, often as the major component in big multi-channel systems. The large data volume makes the optimization of operating parameters necessary. This article reports a study of a method to extend the dynamic range of an 8-bit FADC from the nominal 2 value. By comparing the integrated pulse area wi...
Results from tests characterizing the performance and radiation hardness of the HS9008RH flash analog to digital convertor (FADC) are presented. These tests were performed primarily to evaluate the suitability of this device for use 1n the GEM Central Tracker at the SSC experiment . Basic performance characteristics and susceptibility of these characteristics to radiation were examined . Perfor...
Importance measures are widely used in reliability engineering. To support system reliability optimization, this paper studies the relationship and changing characteristics of the Birnbaum importance measures (BMs) for different components in binary coherent systems. First, the probabilistic meaning of BM and a modeling method for binary coherent system based on Bayesian network (BN) are presen...
Grid impedance estimation is used in many power system applications such as grid connected renewable energy systems and power quality analysis of smart grids. The grid impedance estimation techniques based on signal injection uses Ohm’s law for the estimation. In these methods, one or several signal(s) is (are) injected to Point of Common Coupling (PCC). Then the current through and voltage of ...
In recent years, impedance measurement method by piezoelectric (PZT) wafer activesensor (PWAS) has been widely adopted for non-destructive evaluation (NDE). In this method, theelectrical impedance of a bonded PWAS is used to detect a structural defect. The electro-mechanicalcoupling of PZT materials constructs the original principle of this method. Accordingly, the electricalimpedance of PWAS c...
