The X-IFU is one of the two instruments of the ESA ATHENA mission, offering an unprecedented high spectral resolution. In the detection and readout chain of the X-IFU, the first warm stage is the WFEE subsystem. It mainly includes low-noise amplifiers and current sources to read out and bias cryogenic stages. Based on the development of four previous versions of the ASICs dedicated to the WFEE, a new version has been recently developed to transfer analogue functions to a thinner SiGe technology node of 130 nm. This paper updates the development of this new ASIC.
