    abstract = {Researchers attempt to describe a charge-sensitive preamplifier for fast pulse 
  processing. The charge sensitive preamplifier uses a capacitor in place of the 
  feedback resistor. The input capacitance of this circuit is C<SUB>in</SUB> = 
  AC<SUB>f</SUB>, where A is the open-loop gain of the op-amp. If the op-amp gain 
  is high enough that C<SUB>i</SUB>&lt;&lt;C<SUB>in</SUB>, the external capacitance 
  can be neglected. The charge Q is stored onto the feedback capacitor C<SUB>f</SUB>, 
  producing an output pulse of height V = -Q/C<SUB>f</SUB> independent of the 
  detector and stray capacitances. Since, there is a high voltage on the detector 
  electrode, the amplifier input is connected to the cathode of the GM detector 
  through a ground full-up resistor.}
