Abstract
Presents a general analysis of the upper and lower bounds for the natural frequencies of operational transconductance amplifier (OTA)-C fully integrated continuous time filters. They start by determining the bounds for general structures, and follow by analyzing the most important filter structures, namely, the ladder simulation and biquadratic structures. Practical considerations are discussed, and design equations are presented
