  Picosecond-level timing will be an important component of the next generation
of particle physics detectors. The ability to add a 4$^{th}$ dimension to our
measurements will help address the increasing complexity of events at hadron
colliders and provide new tools for precise tracking and calorimetry for all
experiments. Detectors are described in detail on other whitepapers. In this
note, we address challenges in electronics design for the new generations of
fast timing detectors
