Dynamic translinear circuits - an overview

Dynamic translinear circuits and log-domain filters form a promising and challenging approach to meet the dynamic range limitations that conventional analog implementation techniques are facing due to ever lower supply voltages, low power consumption and high-frequency demands. This paper aims to give an overview of this young, yet rapidly developing, circuit paradigm. Emphasis is placed on methods for analysis and synthesis and on state-of-the-art results obtained for both linear and non-linear applications.
