Dynamic translinear circuits - An overview

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