Abstract
A single-ended to differential linear current driver has been designed and implemented in a 0.25 mum CMOS technology. This full-custom cell is intended for analogue data transmission in large-scale High-Energy Physics (HEP) experiments in the future CERN's Large Hadron Collider (LHC). Intrinsic technology radiation tolerance and specific design methodologies qualify this device to operate over 10 years in the LHC high radiation environment. High linearity and low power-overhead are achieved through a local feedback input stage and a current push-pull output stage. Linearity error is less than 0.1% in the specified operating range and 1% in close to full-swing operation. Static, dynamic and noise performance have been proven to be stable after a total ionising dose of 20 Mrad (SiO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> ) and after accelerated annealing
