µs.
The charge amplifier is an operational amplifier whose positive and nega-
tive inputs are the outputs of the two electrodes. A resistor is placed between
one electrode and the positive input. A parallel resistor, R
f
, and capacitor,
C
f
, are connected as a feedback loop between the amplifier’s output and its
negative input. In this manner, the current output of the sensor, whic ...
