Abstract
A multichannel front-end readout electronics (MFEE) has been designed for readout in detectors in the heavy ion facility in Lanzhou (HIRFL) and the high-intensity heavy-ion accelerator facility (HIAF). With 40 different adjustable gains, this MFEE can meet the need for most of the experiment. One MFEE can read and process the output signals of 128 channels of a detector at the same time. MFEE is based on the AD8488 chip and uses Xilinx Kintex 7 series FPGA, combined with the periphery circuits design, to complete the detector's output charge signal readout. This paper will discuss the design and performance of the MFEE.
