This paper proposes a low voltage (±0.55V supply voltage) low power (44.65μW) high common mode rejection ratio (CMRR) differential amplifier (d.a.) with rail to rail input common mode range (ICMR), constant transconductance (gm) and enhanced frequency performance. Its high performance is obtained using a simple negative averaging method so that it cancels out the common mode input signals at th...
Sound is an effective exogenous factors which affecting human brain processing mechanisms. This research was quasi experimental study that was carried out among 70 students to evaluate the effect of sound frequency on human noise annoyance. Noise annoyance degree was measured during exposure to sound at various frequencies of 500, 1000, 2000, 4000 and 8000 Hz. Sound.exe software was used to det...
Complex sympathovagal interactions govern heart rate (HR). Activation of the postjunctional beta-adrenergic receptors on the sinus nodal cells augments the HR response to vagal stimulation, whereas exogenous activation of the presynaptic alpha-adrenergic receptors on the vagal nerve terminals attenuates vagal control of HR. Whether the alpha-adrenergic mechanism associated with cardiac postgang...
the efficacious effects of pulsed electromagnetic field (pemf) under the certain field parameters like frequency and the field intensity have been reported for various tissue and molecules. since collagen is found abundantly in most tissue structures, this research was designed to further investigate the effects of extremely low frequency (elf) pemf on the synthesis of the epidermal collagen. t...
This paper analyzes the performance requirements that need to be met by a clock generator applied low-temperature quantum computer and negative effects on circuit under conditions. In order meet proposed in this suppress brought about low temperature, for ultra-low-temperature computing is designed. designed using F-CLASS Voltage Controlled Oscillator (VCO), power filter, tail resistor, differe...
The aim of this investigation is to compare the effect of applying two transcutaneous electrical nerve stimulation (TENS) current with different frequencies (2 Hz & 100 Hz) on Hoffmann reflex recorded from gastrosoleus muscle of healthy people. Forty female subjects between 20 to 30 years of age were participated in this quasi-experimental design. Twenty of them were exposed to the 100 Hz curre...
