Description
LEGEND is a ton-scale $^{76}$Ge-based experimental program to search for neutrinoless double-beta
decay with the discovery potential at a half-life greater than 10$^{28}$ years. The discovery of this decay
would establish that the neutrino is its own antiparticle, which would have several implications in explaining the matter-antimatter asymmetry in our universe. The first stage, LEGEND-200, using 200 kg of
enriched HPGe detectors, is under construction at LNGS. Data taking will start in 2021. The
unique LEGEND configuration in which the HPGe detectors operate directly in liquid argon cryostat, as well as the requirement of very low radioactive background, introduces several constraints on the design of the
detector read-out electronics. In this contribution, the design and the performance of the signal readout
electronics for LEGEND-200 will be presented.
