Abstract
We have developed an analog front-end electronics, called LTARS2018[1], for TPC-applications, targeted at dual-phase liquid argon TPCs for neutrino experiments and negative-ionμ- TPCs for directional dark matter searches. This electronics have a wide dynamic range for input charge up to 1600 fC and a function to output a signal with an appropriate time constant for signals having various peaking times, these unique properties may make the LTARS2018 multi-purpose. In this paper we will report results of the LTARS2018 performance check at room temperature and liquid argon temperature. In addition, we discuss the design concept and characteristics of a new electronics (LTARS2020) that been modified to improve performance in liquid argon.
