Abstract

The X-ray Integral Field Unit (X-IFU) of the ATHENA space observatory is based on a 3 kilo-pixels array of superconducting micro-calorimeters, that is read out with the Warm Front-End Electronics (WFEE) and then followed by the Digital Readout Electronics (DRE) outside the cryostat. We have developed low-noise/lowdrift amplifiers for this readout as well as performed simulations and measured the noise, bandwidth, linearity, harmonic distortion and thermal drift. Here we are presenting a realistic model of these parameters. These characterizations and models of the WFEE are necessary in order to get a full ATHENA X-IFU readout chain simulator. Impact of the WFEE low-frequency noise and its limited bandwidth on the entire X-IFU detection chain in Time Domain Multiplexing will be introduced.
