    amplifying the output of a capacitance bridge

    hello all, I want to amplify the output voltage of the bridge(ΔVo) in the circuit which is attached. The amount of capacitances are 47 nanofarad in balanced state & the power supply is a sine wave with frequency of 2.6MHz & amplitude of 0.8 volt. I used a xr2206 ic for producing the sine wave...
