A large-scale prototype with a SiPM tracking plane has been built. The primary electron paths can be reconstructed from time-resolved measurements of the light that arrives to the SiPM plane. Our approach is to measure how many photons have reached each SiPM sensor each microsecond with a gated integrator. We have designed and tested a 16-channel front-end board that includes the analog paths and a digital section. Each analog path consists of three different stages: a transimpedance amplifier, a gated integrator and an offset and gain control stage. Measurements show good linearity and the ability to detect single photoelectrons. %K Neutrino less double beta decay %K Xenon gas TPC %K SiPM readout %K Front-end electronics %K Gated integrator %R 10.1016/j.nima.2011.12.057 %U https://doi.org/10.1016/j.nima.2011.12.057 %P 229-232
