Question 24
INNAT1 markNeeds review
The capacitance
of a capacitive type sensor is
pF, where
is the input to the sensor. As shown in the figure, the sensor is excited by a voltage
V. The other terminal of the sensor is tied to the input of a high input impedance amplifier through a shielded cable, with shield connected to ground. The cable capacitance is 100 pF. The peak of the voltage
at the input of the amplifier when
(in volts) is ____.
