Highly Efficient Envelope-Tracking Modulator Over Wide Output Power Range for Dual-Mode Power Amplifier
This paper presents a highly efficient envelope-tracking (ET) modulator over wide output power range. The ET modulator is designed to operate with a dual-mode power amplifier (PA). The supply voltage of the linear regulator is adjusted according to the average power level for further enhanced efficiency at a low power region. An adaptive bias circuit is designed to avoid the crossover distortio...

متن کاملVein of Galen Aneurysmal Malformation and High-output Cardiac Failure in a Newborn
Background: Vein of Galen aneurysm (VGA) is the most common form of symptomatic cerebrovascular malformation in neonates. It develops in a fetus in the first trimester of pregnancy due to unknown reasons, but it is likely to have a genetic etiology. The prognosis of VGA is usually poor, particularly in newborns with heart failure due to high-flow intracerebral shunt. Surgery and endovascular em...
متن کاملExternal cardiac defibrillation during wet-surface cooling in pigs.
OBJECTIVE During surface cooling with ice-cold water, safety and effectiveness of transthoracic defibrillation was assessed. METHODS In a pig ventricular fibrillation cardiac arrest model, once (n = 6), defibrillation was done first in a dry and then in a wet condition using the ThermoSuit System (Life Recovery Systems, HD, LLC, Kinnelon, NJ), which circulates a thin layer of ice-cold water (...
متن کاملInotropic support during cardiac surgery.
extremely claustrophobic conditions, the nature of the patient's illness, and the requirements for patient compliance during the procedure followed by a rapid recovery. There is a paucity of information on how this can ideally be achieved. Propofol would appear to satisfy these requirements, but its unpredictable effects on involuntary movements precludes its use. The regimen suggested by Dr Gr...
