The advent of the first demonstrators for quantum computing increased remarkably the interest towards the design and use of CMOS at deep cryogenic temperatures, which pave the way for the implementation of low thermal noise electronics for the readout and control systems for the qubits. In the field of fundamental research, specifically for dark matter search and neutrinos, the widespread R&D on cold-CMOS became enabling for the development of multi-channel integrated readout electronics for LAr or LXe based detectors. The mild conditions of such detectors, respectively 87 and 165K, undoubtedly explore a different temperature range for the operation of the readout electronics, in respect to what is commonly considered for the control system of the qubits, typically operating at LHe boiling temperature (4.2K).

We will analyse the opportunities and perspectives for the development of cryogenic electronics for astroparticle physics experiments, discussing the opportunities and challenges in terms of reliability and scalability of future multi-ton detectors.  We will start from an overview and partial review of the wide amount work already done in the field of CMOS modelling and design for cryogenic operation. The seminar will then focus on detectors employing silicon photomultipliers and associated readout electronics, based on examples of R&D proposed by the community and providing an insight on designs and technology developed at INFN.
