= In the following circuit, a capacitive sensor is modeled by C, in series with resistance Rs. An identical sensor is used as a dummy unit to compensate for the undesired noise. A 5-V 400Hz source is used to bias this arrangement. It is given that Rs = R₁ 10 Q2, R₂ R3 = 1 kQ, and nominal capacitance of sensors is 10 pF. (a) Determine the baseline of the system. (b) If the active sensor capacitance Cs changes by ±0.5 pF then determine the output voltage.
