thank u for ur help and giudance
I followed the steps that u mentioned 4 increasing the range( actually i did 1st and 2nd steps) and it works....
but the 3rd step which is converting the inverting op-amp in the reciver part to the non-inverting isn't clear 2 me.... I understood the purpose of using noninverting rather than inverting op-amp... but I don't know how to do it ... i know that the terminal 1 should be grounded .. if i am not wrong ... but I don't know what is the specification that i have to consider ... I ask u if u can provide me more details about the 3rd step ......
thnks again .. i appriciate ur help
kind regards

Does replacing the exciting op-amp with this type(10Mhz) need any further change to the circuit? !!!
i am still waiting for non-inverting op-amp circuit that can be replaced by the exicting one...
