The IXO/XMS instrument baseline is an array of TES sensors. Alternatively, we are now developing a micro-calorimeter array based on Silicon doped sensors. Our strength stands in a very low power consumption at 50 mK, allowing more than 4000 readout channels in the limited power budget of the IXO/XMS cryostat, for a Field of View as large as 6'x6' square while keeping the same spectral resolution. In parallel, we develop the cold (2-4K) frontend electronics based on High Electron Mobility Transistors (GaAlAs/GaAs) and SiGe ASIC electronics to readout, amplify and multiplex the signals. We present the status of our development and our current design study.
