Paper Abstract

A simple, low-cost, low-noise preamplifier has been developed for use with Reticon self-scanning diode arrays or similar devices. This design lends itself naturally to quasi-CDS (correlated double sampling) signal processing, allowing system bandwidth and noise to be effectively limited without resort to pulse shaping networks. The preamplifier seems potentially capable of approaching the fundamental noise level imposed by the detector itself. With minor modification, it can be operated from several kHz up to about 1 MHz pixel frequencies.
