SQUIDs and their read-out electronics for application with a hot-electron bolometer are considered in detail. This results in a theoretical trade-off study between a Hypres two-stage DC-SQUID, APF, DROS and an Oxford Instruments' Internal Relaxation Oscillation Mode SQUID. The study shows that only a Hypres DC-SQUID can meet the requirements on noise, dynamic range and speed as derived from the application for an X-ray micro-calorimeter. The scope for redesign of the other types of SQUID is addressed.
