The ATLAS upgrade will require more efficient electronics to fulfil the new performances expected by the experiment. Concerning the readout electronics of the Tile Calorimeter, the replacement of the 3in1 board by an integrated circuit is under study. The proposed circuit is composed of a multi-gain current conveyor, followed by shapers, an integrator for the calibration and an analog-to-digital converter. This solution presents better performances, concerning the noise, and the power consumption. Two prototype chips have been submitted using the IBM 130nm CMOS technology: one with a three gains current conveyor, another with an enhanced current conveyor associated with shapers.
