· View raw image Shown is the schematic diagram of a charge amp. The ambient electric field E induces charge (Q) on the sensor plate which is measured by the charge amp.The output voltage is given by V o = Q/C.The feedback resistor (R) slowly bleeds off charge from the capacitor keeping the output from saturating.This also sets the high-pass cutoff frequency of the circuit at 1/RC.
