Abstract

In this paper we analyse the properties of the Bloch oscillating transistor as a preamplifier in cryogenic devices. We consider here especially the readout of hot electron bolometers (HEBs) based on Normal-Superconductor-Insulator tunnel junctions, but the results also apply more generally. We show that one can get an equivalent noise voltage below 1 nV/&sqrt;Hz with a single BOT. By using N BOTs in a parallel array configuration, a further reduction by factor &sqrt;N may be achieved.
