    The radiation hard design of a low noise, 500 MHz, 0.13 µm CMOS front-end for a LIght Detection And Ranging (LIDAR) receiver with mm accuracy is presented. The design features enhanced tolerance to radiation induced threshold voltage shifts by employing a current steering compensation mechanism. In order to generate an accurate timing point, independent of the amplitude of the input signal, a new Current- Mode-Gain-Control (CMGC) structure was developed using a replica-based current divider. The design was simulated using a worst-case design methodology, which is developed to facilitate the design and evaluation of analog circuits that are robust to parameter shifts induced by ionizing radiation, temperature drift or intrinsic process variations.
