A Wide-Band Electrometer Amplifier
I. Pelchowitch, J. J. Zaalberg van Zelst · Review of Scientific Instruments · 1952
It is shown that by appropriate feed-back methods it is possible to construct a wide-band electrometer amplifier with a stable flat-response characteristic. By analysis the signal-to-noise ratio has been found to be most favorable in the case where the mean frequency of the amplifier is low. Some practical values of the circuit are given.
