We present a distributed, self-organizing and fault-tolerant readout network Application Specific Integrated Circuit (ASIC) for the high-density electrode array targeting at neutrinoless double-beta decay search in Time Projection Chamber (TPC). A meter-sized plane tiled by approximately 1 x 10(5) single-electrode Topmetal-S sensors with a pitch of 5 similar to 10 mm is utilized to realize charge readout plane in a ton-scale high-pressure gaseous TPC. A sensor network is proposed under the premise of ensuring the tightness and radioactive purity of the high-pressure TPC. As a node of the netwo...
