Abstract

The low noise preamplifier described in this paper presents, as a distinguishing feature, a difference input with a common-mode rejection ratio which at 1 MHz is still higher than 70 dB. It has been primarily conceived to cope with the operation requirements of some nuclear radiation detectors in noisy environments, and of Johnson thermometry. Being very versatile, however, it can be succesfully employed in several other domains of scientific investigation involving signal acquisition from low-level wideband transducers and detectors when the main aim is the minimization of noise of both deterministic and stochastic nature.
