Part of the Lecture Notes in Electrical Engineering book series (LNEE, volume 558)


This Chapter presents a novel logarithmic analog-to-digital conversion architecture comprising a time-to-digital converter and voltage-to-time conversion elements based on cross-coupled inverters. The voltage-to-time conversion element with a logarithmic conversion characteristic and the main sources of nonlinearity will be studied in this Chapter.
