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

BlackBerry Wraparound Display Phone

on
This BlackBerry concept smartphone includes a wraparound display which allows users to call and send texts on one side of the phone and play games and take photos on the other side.

 


Submitted by BlackBerry fan (and Industrial Designer w/ an MBA) John Anastasiadis, John's BlackBerry Concept is absolutely stunning. 
Here are the key specs/aspects of the phone as John sees them:

  • Wrap around screen. This allows you to incorporate soft-keys on the underside for gaming, navigation, etc.
  • The asymmetrical shape allows you to know the orientation of the phone (while holding) without having to look at it.
  • There is one hard button that serves multiple functions (screen lock, picture taking, etc.)
  • The phone has some artificial intelligence that can predict if you intended a command. For example, sometimes while using an iPhone it will slip out of my hand, causing me to grab for it any which way I can, thus hitting all sorts of buttons on the screen.
  • The front and back cameras are behind the screen. The screen will illuminate to act as the flash.
 my hats off to the amazing designer:):)
