USING FIGURES-OF-MERIT TO EVALUATE MEASURED A/D-CONVERTER PERFORMANCE

Bengt E. Jonsson

Abstract

This work surveys various figures-of-merit (FOM) that have been used to evaluate and compare measured ADC performance, and takes a first step towards a systematic classification and analysis. Strengths and weaknesses associated with selected figures-of-merit are discussed, and their potential sweet spots or parametric bias is examined using a combination of theoretical analysis and a near-exhaustive set of scientifically reported experimental data. A commonly used FOM is shown to have a distinct, and highly predictable sweet spot with respect to ENOB, and a strong bias towards scaled manufacturing technologies. It is therefore concluded that a continued discussion and treatment of the topic is motivated.
