A. Alessandrello et al., DIFFERENTIAL, VOLTAGE-SENSITIVE PREAMPLIFIERS FOR BOLOMETRIC DETECTORS, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 370(1), 1996, pp. 220-222
We present two differential voltage sensitive preamplifiers to read-ou
t very slow and fast cryogenic detectors. The first one operates at ro
om temperature, while the second one, made in a monolithic GaAs MESFET
process, is optimized for 4.2 K.
