Hi , I am really fixed on this thing. Let me explain my application in brief. I have a inductive proxi switch and I want to convert this into analog Inductive sensor. So right now i am sensing the current which flows through the oscillator when the target approaches the sensor . This is ok and the plot is exponential . Now the difficult task is to convert this voltage into the range of 1 to !0 Volts . As the plot is non-linear it has become very difficult for me to convert this into linear 1-10V. Also I cannot use the digital technique because of size. vdd ???
