Accepting Preamplifier Pulse Shapes
The linear, pulse-shaping amplifier must accept the output pulse
shapes provided by the preamplifier and change them into the pulse
shapes required for optimum energy spectroscopy. Two general types
of charge-sensitive preamplifiers are in common use: the
resistive-feedback preamplifier,* and the
pulsed-reset preamplifier.
Each of these places slightly different demands on the amplifier's
functions.
* Pulse shapes from a parasitic-capacitance preamplifier are similar
to those from a resistive-feedback, charge-sensitive preamplifier. |
