Abstract :
This paper presents a method for the successful design of high resolution cascaded continuous time EA modulators. Therefore performance limiting aspects are considered analytically and through simulation. A previously introduced simple method for RC-error cancellation is investigated and extended to cancel errors due to finite gain bandwidth. Finally we present a high-level system, which can be integrated following the proposed way to achieve high-performance cascaded continuous time modulators
