Complex impedance, responsivity and noise of transition-edge sensors: analytical solutions for two- and three-block thermal models
arXiv:1205.5693 · doi:10.1063/1.4759111
Abstract
The responsivity and noise of a voltage-biased superconducting transition-edge sensor depends strongly on the details of its thermal model, and the simplest theory for TES response assumes a single heat capacity connected to the heat bath. Here, analytical results are derived and discussed for the complex impedance, the responsivity and the noise of a transition-edge sensor, when the thermal model is not simple but consists of either two or three connected heat capacities. The implications of the differences of the models are discussed, as well.
