This paper presents a 12b 180 MS/s partial-interleaving Pipelined-SAR analog-to-digital converter (ADC). The 1st-stage is implemented with a 2b/cycle SAR ADC for high speed, where we propose a merged-residue-DAC technique to improve the noise performance. The capacitor pre-charging in conventional 2b/cycle operation wastes settling time and switching energy, while with this design approach the ...

This paper presents a direct torque control strategy for double star synchronous machine fed by two three-level inverters. The analysis of the torque and the stator flux linkage reference frame shows that the concept of direct torque control can be extended easily to double star synchronous machine. The proposed approach consists to replace the switching tables by one artificial neural networks...

This chapter provides history of routing to cognitive routing . Firstly i t reviews hardwired routing a kind of switching to dynamic routing for telecommunication network starting with dynamic alternate routing (DAR) to ATM (Asynchronous Transfer Mode) routing. Secondly it presents routing in data network or packet switching. Thirdly it reviews routing for wireless multi hop network with specia...

A signal processing technique is presented by which the position of a rotor supported in magnetic bearings may be deduced from the bearing current waveform. The bearing currents are presumed to be developed with a two state switching amplifier which produces a substantial high frequency switching ripple. This ripple is demodulated using a model reference parameter estimation technique which ext...

Introduction: There is scholarly studies conducted in this field examining the relationship between brand switching with many variables such as promotion, service quality, competition, economy of country etc; results those researchers have provided contradictory arguments. Therefore, main objective current study to identify “brand telecommunication industry among youth and adults Sri Lanka spec...

Introduction: If the patients are not satisfied with the hospital, this results in switching behavior of patients. In this situation, among different hospitals, the patients choose the hospital with higher level of service quality. So, the main aim of this paper is investigating the effect of hospital's service quality on switching behavior of inpatients in Shahid Sadoughi Hospital of Yazd. Me...

The basic idea of the circuit fault diagnosis method based on logic is to establish a computer expert database system first, connect GPIB interface card, and then each intelligent instrument through standard bus. Through connection tested object adapter object, test platform are formed. Based traditional simulation model, this paper improves switching power supply, designs model simulation, dea...

One of the difficulties with PWM switching converters is high switching loss and electromagnetic interference due to switching at non-zero voltage and current, which limits the operating frequency. In order to reduce the converter volume and weight (by increasing the frequency) and reducing switching losses, zero voltage and current switching methods are recommended. In this paper, four main ze...
