In this paper, a second-order 14 bit 2MSPS sigma-delta ADC used for data acquisition is proposed. The adopted feed-forward structure in SDM has reduced more than 50% output swing of integrator, leading to inherent low power operation compared with the ...

This paper presents a design and implementation of a low noise phase-locked loop (PLL) based on ring oscillator to provide timing clocks for the analog-to-digital converter (ADC). The ring oscillator consists of four current control delay cells with ...

This paper introduces the machining principles and characteristics of form grinding cylinder gear as well as the composition of the profile shape of a form disc grinding wheel. By using the non—instantaneous section envelope machining principle, a ...

This paper introduces the machining principles and characteristics of form grinding cylinder gear as well as the solution process of circular arc and continuous least squares circular arc. after the profile shape of grinding wheel is dispersed into n ...

Currently, the wireless sensor networks QoS is confronted with many challenges. Wireless sensor networks has many characteristics, such as basing on the data, and facing application and dynamic characteristics. This paper emphatically analyzes the ...

A compression approach of power quality monitoring data based on two-dimension Discrete Cosine Transform (DCT) is presented to deal with huge data about power quality event detection. The monitoring data was truncated and recomposed in multiple cycles ...

In this paper, a novel hysteresis current control method based on the phase of the output of voltage loop by using a single LEM current sensor is proposed. Because of having two filter inductors, the Dual Buck Half Bridge Inverter has on bridge arm ...

An automatic registration algorithm for the scattered point clouds is proposed in this paper. The curvature of each point is estimated by using the quadratic surface fitting method. And then, according to the change of curvature the feature points that ...

The key idea of the lifting scheme is constructed wavelet filters by several predict operators and update operators. We know that the poly-phase matrix can be factored into finite matrixes, and these matrixes can be regarded as the predict operators and ...

In order to achieve remote control of service robots, a wireless intelligent control system is designed by combining radio frequency technology, MCU, ultrasonic sensor technology, image sensors and personal PC. Voice broadcasting, barrier avoiding by ...

The idea of text to speech by a computer is an enhancement of the human learning ability. Due to the fact that each person has individual ability of visualization, the receiving of information in the form of voice helps make everything become easier. ...

A discrete particle swarm optimization (DPSO) algorithm is presented for the assembly line balancing problem of type 1, ALBP-I. A new permutation encoding method is developed to make the particle correspond to a feasible operation sequence (FOS) which ...
