Using a simple and well-known voltage-to-current transformation, current-mode active RC filters that are amenable to IC realization can be derived from their voltage-based counterparts. Using this transformation, a classification of current-based single-amplifier biquads is introduced which is derived from a similar voltage-based classification. This classification is exhaustive in that it includes all possible current-based single-amplifier biquads
