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

Lavnav helps you aim straight at night

on

Do you envy those who are able to sleep through the night without having to worry about getting up halfway in the middle in order to take a leak? Well, I suppose all the shuffling around is all right when you’re single, but some of us who are married might have spouses who are light sleepers and do not take it too kindly whenever you keep on getting up and turning on the lights just to get some relief from all the pressure that’s building up in your bladder.

Well, how about getting the �16.99 Lavnav instead? Yes sir, this unique gizmo will do away with the unpleasant experience of getting yourself half-blind when you turn on the bathroom lights with a 1,000-watt light bulb in place. All you need to do is stick the Lavnav onto the inside of your lavatory and you’re good to go – after all, the motion sensor kicks itself into action the moment it detects anyone within the vicinity. Heck, when the seat is up, it will be red in color, but goes green when the seat is left down.
Powered by a couple of AA batteries, we suspect you won’t be changing these batteries anytime soon for sure.
