Abstract :
A new procedure for obtaining cascadable, opamp based current-mode biquads from voltage-mode biquads without the use of voltage-mode to current-mode transformations is presented. Two new multi opamp biquads circuits are derived and used to construct lowpass, highpass, bandpass, notch, and allpass filters. A single opamp bandpass circuit is also derived. Laboratory results are provided
