A simple capacitance amplifier circuit is shown in the figure. A. C1 represents a capacitive sensor whose nominal value is 50 pF. C2 is a fixed capacitor of 25 pf. Find the output voltage if the sinusoidal excitation voltage is 1V peak-to-peak at frequency 1kHz. Assume the op. amp. to be an ideal one.
