need help on sensor signal conditioning circuit

[avlsi]

I have a sensor whose resistance varies by 1% for a desired input and the undesired input.can anyone suggest me any signal conditoning circuits.

First tell us the value of the resistor, and a little more explanation of your system, specially about the undesired input.

Hello,
One can use a bridge circuit,or an instrumentation amplifier. The choice will depend upon the common mode voltage.Also one can use an appropriate filter.
Hope it has been of some help. One needs specific details of your circuit for further help.

HI DEAR,

PLEASE TELL ME THE DESCRIPTION OF YOUR SENSOR AS WELL AS FOR WHICH PURPOSE YOU WANT TO USE.

 

[avlsi]

I donot have any specification of the sensor. I am aksed in a way to design for a device that is non existing.I will get only the electrical specifications.

I would like to know references on the usage of wheatstone bridge. And also on instrumentation amplifier.

Thanks in advance.

Added after 1 minutes:

resistance is in the order of GIGA OHMS.
