Hi Folks
Thanks for all the responses so far.
I've created an oscillator and the two (out of the three) capacitors that form the Twin T oscillator are actually sensors that I have created for a project.
The final aim is that as the capacitance changes due to certain parameters, the oscillator frequency changes, which has to be picked up. Now, the reality is that the change in capacitance is pretty small (0.01 pF), and I would still want an appreciable change in frequency because of that. (I am operating at 1 MHz).
Any tip or ideas, on how to achieve that ?
