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

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

More tablets, PCs, and TVs to adopt AMOLED displays


 
AMOLED (active matrix organic light emitting diode) displays are ideal for tablets and TVs as they offer high contrast ratios, quick response times, and wide viewing angles. The technology also allows for such devices to be thin, flexible, and even transparent, the research firm notes.
On the other hand, AMOLED technology has faced challenges scaling up to screen sizes much larger than those on smartphones. But the latest improvements in the technology are expected to pave the way for its use on bigger devices, though production can still carry a high price tag.
"OLED displays operate through direct emission, as opposed to transmissive LCD or reflective displays, which enables area lighting," Jennifer Colegrove, vice president of emerging display technologies for NPD DisplaySearch, said in a statement. "The technology has made good progress and is ready to enter large-size applications, but low cost manufacturing for large sizes is still a challenge."


In December Samsung released a 7.7-inch Galaxy Tab tablet that uses a Super AMOLED Plus display. LG is expected to launch a 55-inch OLED TV sometime this year.
And NPD DisplaySearch sees other tablet and laptop vendors adopting the technology in 2012 as the manufacturing process starts to allow for larger displays in a more cost-effective way.
Revenue from OLED displays overall might have surpassed $4 billion last year, estimates NPD DisplaySearch, around 4 percent of all flat-panel display sales. As more companies latch onto the technology, revenue could shine past $20 billion by 2018, accounting for 16 percent of the entire display industry.
