Question 1 (5 marks) Consider a capacitive Wheatstone bridge circuit with two fixed capacitors
(C_(0))and a differential capacitor pair
(C_(w1)&C_(w2))also with parasitic capacitance CP. The fixed capacitor's electrode is
200\mu m\times 200\mu mand two parallel electrodes are overlapped
100%. The gap between two electrodes is
3\mu mand it is filled with air. If
\Delta Cis
1fF,CPis
1pF,Vis 1 V , what is the Wheatstone bridge circuit's output voltage
