This paper presents a general analysis of the upper and lower bounds for the natural frequencies of OTAC fully integrated continuous time filters. We 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, design equations are presented.
