A high-linearity and high-speed current-mode sampleand-hold circuit is designed and simulated using a 0.25μm CMOS technology. This circuit design is based on low voltage and it utilizes a fully differential circuit. Due to the use of only two switches the switch related noise has been reduced. Signal dependent -error is completely eliminated by a new zero voltage switching technique. The circui...

Increasing demand experienced by electric utilities in many parts of the world involving developing country is a normal phenomenon. This can be due to the urbanization process of a system network, which may lead to possible voltage decay at the receiving buses if no proper offline study is conducted. Unplanned load increment can push the system to operate closes to its instability point. Variou...

Noninvasive detection is a fundamental prerequisite for pervasive healthcare system and biosensing. Along with different noninvasive techniques such as ultrasound, X-ray, magnetic resonance and optical imaging, electrical impedance spectroscopy is emerging as more suitable technique for tissue level diagnosis. This paper presents a noninvasive technique for bioelectrical impedance estimation by...

Introduction:  Electroporation  is  a  technique  for  increasing  the  permeability  of  the  cell  membrane  to  otherwise  non-permeate  molecules  due  to  an  external  electric  field.  This  permeability  enhancement  is  detectable if the induced transmembrane voltage becomes greater than a critical value which depends on the  pulse  strength  threshold.  In  this  study,  the  variabil...

This study presents the performance evaluation a developed energy harvesting interface circuit in active technique.

Circuit designs and simulation results are presented for a conventional diode rectifier with voltage doubler in passive te...

This paper presents an effective technique to monitor and predict the open circuit voltage (OCV) for lead-acid battery cells. The underlying principal of the technique described in this paper employs one simple equation to predict the equilibrated cell voltage after a small rest period. The technique was tested and analyzed using results obtained from experiments conducted at the Yuasa Battery ...

This paper presents a study of the power factor improvement in single phase ac voltage controllers through various methods. The overall efficiency is improved by some advanced methods. This analysis about power factor correction can be utilized in learning process. On the basis of power factor improvement, this paper compares two methods. One method is a modified phase angle control (PAC) techn...

voltage stability may be improved by various control functions. in this paper, it is shown that how high side voltage control (hivc) may be employed for this purpose. two test systems, namely a 22- bus and ieee u8-bus systems are used to demonstrate the proposed tuning strategy for hsvc control parameters.
