英文摘要：
  At the China Jinping Underground Laboratory, the Particle AND Astrophysical Xenon phase IV (PandaX-4ton) in planning is a dark matter direct detection experiment with dual-phase xenon detector as an upgrade of the second phase of the experiment, PandaX-II. In this paper, the prototype of the front-end electronics of PandaX-4ton is presented. The front-end electronics consist of the high-gain preamplifier cards and the eight-channel digitizers with 14-bit resolution and 1 GSps sampling rate for waveform digitization. The clock synchronization circuit within the digitizer is well-designed to align all the PMT channels. The digitizer also contains gigabit fiber to exchange data with trigger and data acquisition system. The specification of effective number of bits f the digitizer is about 9.7 b at 148 MHz, and the integral nonlinearity of the digitizer ranges from -4 least significant bit (LSB) to +4 LSB, and the differential nonlinearity ranges from -0.6 LSB to +0.6 LSB. The performance of the front-end electronics can meet the requirements for the PandaX-4ton.
