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

LG Optimus 4X HD

LG Optimus 4X HD :)

 Quad-core Tegra 3:)

 Ice Cream Sandwich:)

 4.7-inch display:):)

 

If LG failed to impress so far with the Android 2.3 phones it's shown off in the run up to MWC 2012, perhaps the Optimus 4X HD can turn things around. This 4.7-inch beast will hit Europe in the second quarter and is its first to feature a 1.5GHz quad-core Tegra 3 as its benchmark destroying CPU, a 4.7-inch True HD IPS LCD (1280x720) plus what appears to be a lightly customized version of Ice Cream Sandwich. Perhaps the only logical followup to its Optimus 2X that kicked off all the dual-core madness, it also includes a 2,150mAh battery, 1GB of RAM and 16GB of internal storage. Despite that huge screen, at a depth of 8.9mm it's only slightly thicker than the superwide 4x3 Optimus Vu. Just like the Fujitsu prototype we spent some time with at CES, the Tegra 3 features a 4+1 "Companion Core" design, with a fifth low power unit available to take care of more mundane tasks without draining the battery. This is all pretty close to the leaked "X3" specs we'd heard, however there's no mention of NFC or HSPA+ just yet, only DLNA and MHL. Check out the full press release after the break for a few more specs.
