OSTI ID:6207422
A new concept of paralleling input stages was developed to meet the requirements for a low-noise, wideband preamplifier that matches the transmission-line impedance of ultrahigh-sensitivity fission counters. The prototypic preamplifier consists of four dual-feedback-path amplifiers and a summing amplifier. It has an 18-pA/..sqrt..Hz equivalent input noise current density, a 60-MHz bandwidth, a 25-..cap omega.. input impedance, and a 5-k..cap omega.. transimpedance.
