One-input, Three-output, General-purpose Biquadratic Filter using all Positive CCIIs

In this paper we present a two-integrator, Bi- quadratic CCII filter, which consists of all-positive CCIIs with grounded components, which makes it suitable for integrated circuit realization. The circuit has low sensitivity to component tolerances, low output thermal noise, and the capability of orthog- onal tuning of filter parameters. A step-by step design procedure for a fourth-order band-pass filter with optimum dynamic range is proposed. Breadboard laboratory designs displayed excellent results.
