title = "SQUID readout and flux feedback based ona a SiGe bipolar transistor at 4.2K",
abstract = "I have experimented with a SiGe heterojunction transistor at 4.2 K acting as a readout amplifier for dc SQUIDs. Flux noise level of 0.35 0 / Hz was reached with one SQUID type. Slew rate of 1.7 107 0/s was observed with another SQUID type in a flux feedback arrangement having a calculated >108 0/s slew rate. The SiGe transistor dissipated 9 mW at 4.2 K, but dissipation levels in the 0.1 mW range appear feasible.",
