i ABSTRACT The partially-depleted (PD) silicon Metal Semiconductor Field Effect Transistor (MESFET) is becoming more and more attractive for analog and RF applications due to its high breakdown voltage. Compared to conventional CMOS high voltage transistors, the silicon MESFET can be fabricated in commercial standard Silicon-on-Insulator (SOI) CMOS foundries without any change to the process. T...

This paper deals with the performance analysis of static compensator (STATCOM) based voltage regulator for self excited induction generators (SEIGs) supplying balanced/unbalanced and linear/non linear loads. A threephase insulated gate bipolar transistor (IGBT) based current controlled voltage source inverter (CC-VSI) known as STATCOM is used for harmonic elimination. It also provides the requi...

The effects of proton and gamma radiation are compared for several types of integrated circuits with complex internal design and failure modes that are not as straightforward as the input bias current mechanism that is frequently used to study damage effects in linear devices. New circuit failure mechanisms were observed in voltage regulators that cause them to fail at much lower levels when th...

BACKGROUND Left ventricular remodeling (LVR), an increase in left ventricular end-diastolic volume index > or = 20%, is an adverse consequence of myocardial infarction. The aim of this study was to assess the association between LVR and adiponectin, which has been shown to protect against myocardial ischemia-reperfusion injury. METHODS In 75 patients echocardiographic examination was performe...

BACKGROUND Long term effects of left ventricle (LV) repair surgery (LVR) for ischemic cardiomyopathy are not well understood. METHODS AND RESULTS Sixty-nine rats developed ischemic cardiomyopathy with large akinetic LV area 4 weeks after the left anterior descending artery was ligated. In a second surgery 4 weeks later, 33 rats underwent LVR by plication of the akinetic LV area (LVR group), a...

BACKGROUND Left ventricle remodeling (LVR) is regarded as a marker of unfavorable outcome in patients following acute myocardial infarction (AMI). Repolarization, especially its late part (TpeakTend), is strongly related to local myocardial attributes. We assessed prospectively in this study if repolarization duration (measured from one hour of nighttime) might predict LVR occurrence in patient...

Low Dropout (LDO) Voltage Regulators are the linear regulators which drives upon a very small differential voltage. The main components of dropout voltage Error amplifier, Pass device, reference source and divider network. low regulator uses variable input to give steady, constantly controlled, low-noise DC output This is that includes drop among as well works even when extremely close amplifie...

OBJECTIVE Spinal cord-injured (SCI) individuals demonstrate an increased baseline leg vascular resistance (LVR). In addition, despite the lack of sympathetic control, an increase in LVR is observed during orthostatic challenges. On the basis of the vasoconstrictive characteristics of angiotensin II, we examined the hypothesis that angiotensin II contributes to the LVR at baseline and during hea...

AIMS Few data are available on the extent and prognostic value of reverse left ventricular remodelling (r-LVR) after ST-elevation acute myocardial infarction (STEMI). We sought to evaluate incidence, major determinants, and long-term clinical significance of r-LVR in a group of STEMI patients treated with primary percutaneous coronary intervention (PPCI). In particular, the role of preserved mi...
