Abstract	Imaging calorimetry at the International Linear Collider requires highly granular and innovative detectors. Technological prototypes have been built and tested under the CALICE collaboration framework and FP6 EUDET, FP7 AIDA European programs. These prototypes are readout by multi-channel chips named SKIROC2, SPIROC2and HARDROC2, designed by the IN2P3 OMEGA group in AMS SiGe 350 nm technology. In this presentation, the ASIC architectures and test results on test bench and at system level will be described as well as first results of test bench measurements performed on HARDROC3, which is the first of the ``3rd generation'' chip to be submitted and where the 64channels are handled independently to perform zero suppress on chip.
