Offset balancing in pseudo-correlation radiometers for CMB measurements

, 2003
Radiometeric CMB measurements need to be highly stable and this stability is best obtained with differential receivers. The residual 1/f noise in the differential output is strongly dependent on the radiometer input offset which can be cancelled using ...
