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 m
and two parallel electrodes are overlapped
100%
. The gap between two electrodes is
3\mu m
and it is filled with air. If
\Delta C
is
1fF,CP
is
1pF,V
is 1 V , what is the Wheatstone bridge circuit's output voltage
