High CMRR Instrumentation Amplifier (Schematic and Layout) design for biomedical applications

on
Instrumentation amplifiers are intended to be used whenever acquisition of a useful signal is difficult. IA’s must have extremely high input impedances because source impedances may be high and/or unbalanced. bias and offset currents are low and relatively stable so that the source impedance need not be constant. Balanced differential inputs are provided so that the signal source may be referenced to any reasonable level independent of the IA output load reference. Common mode rejection, a measure of input balance, is very high so that noise pickup and ground drops, characteristic of remote sensor applications, are minimized.Care is taken to provide high, well characterized stability of critical parameters under varying conditions, such as changing temperatures and supply voltages. Finally, all components that are critical to the performance of the IA are internal to the device. The precision of an IA is provided at the expense of flexibility. By committing to the one specific task of

samsung galaxy s3 vs sony xperia s

on


here i have the given the crisp and clear comparison between the core specs of both the devices to make you see the difference and decide accordingly which smartphone to head towards. though their is not much difference between the 2 phone but in some area like battery,os version and few new features galaxy s3 takes a edge over xperia s which includes a 12mp camera with 16 x flash to give s3 a strong competition in some areas.


so go ahead take a look at the smartness of smart-phones below and enjoy :)
