Pixelated readout for multi-kiloton Liquid Argon (LAr) Time Projection Chambers (TPCs), such as that being deployed for the Deep Underground Neutrino Experiment (DUNE), would enable full 3D-reconstruction of events, in contrast to wire/strip anode readout that is challenged by track disambiguation in 2D track reconstruction. The Q-Pix Consortium, established in 2019, is developing a low-power pixelated readout technique for LAr TPCs based on charge-integrate/reset (CIR) circuits. The CIR blocks generate a sequence of reset pulses with time intervals corresponding to fixed charge integrals, allowing signal reconstruction without continuous digitization. The Q-Pix ASIC, intended for reading out pixel arrays, comprises CIR blocks along with digital components responsible for communication and reconfigurable data routing. This talk will give an overview of the Q-Pix project, its status, and prospects, with emphasis on the development and prototyping of the Q-Pix readout ASICs.
