Increased frequency capability for a given active filter configuration

It is shown that the performance of a given active filter configuration is dependent upon the design procedure employed. Consequently, design procedures may be selected to optimize some aspect of the active filter´s performance. This paper develops design procedures which minimize the effect of gain bandwidth (GB) upon a given active filter configuration. The root sensitivity with respect to the GB can be decreased by a factor of two or more depending upon the realization. The techniques presented are applicable to most single and multiple amplifier, second-order active filter realizations.
