### DESCRIPTION ( Introduce yourserlf and your project)

My name is Alex Zviagintsev

I received the B.S. and M.Sc.degrees from the Technion-Israel Institute of Technology, Haifa, Israel, where I'm currently pursuing the Ph.D. degree in electrical engineering. My current research interests include very large scale integration architectures, analog circuit design, MEMS, and IR sensors and detection.

### TECHNICAL DETAILS (With project photos)

The project deals with IR camera. the signal measurement should be done as a difference between the signal and the refference signal value that should remove the DC pomponent. the problem is that the DC componnent is not constant and changes during the measurement as a result of sensor selfheating.. For solving this problem it is common to use the blind sensor, but this requires sensor area duplication. We propose to make an external compensation implemented in PCB board and thus resolve the problem of DC signal slow flactuation. 

this is summarized in some following publications:
