Abstract
We present a low-cost ultra-low-noise cryogenic amplifier, which has b een developed for the investigation of shot noise suppression and enha ncement in double-barrier resonant-tunneling devices. Results of the n oise measurements performed on the amplifier operating at liquid nitro gen temperature are discussed and compared to those obtained at room t emperature.
