The planned IceCube-Upgrade will enhance the capability of IceCube in the detection of GeV-scale neutrino physics and enable an improved measurement of the properties of the glacial ice. Three types of new optical sensors will be deployed during the Upgrade: PDOM, D-Egg, and mDOM. Since the design of the PDOM and D-Egg are very similar, the development of the front-end electronics for the two optical sensors has been merged. The photo-electron signals detected by the PMTs are digitized with high-speed ultra-low power ADCs and processed in an FPGA, before being sent to the data acquisition system located on the surface of the South-Pole glacier. The almost final revision of the front-end electronics is equipped with the common microcontroller unit and the communication daughter board for simplifying the communication scheme for the three different modules. This contribution focuses on the design of the front-end electronics and presents first results from the performance tests. : Presented at the 36th International Cosmic Ray Conference (ICRC 2019).
