A new topology for the realization of MOSFET‐C integrated biquadratic filters is proposed which uses an MOS differentiator with non‐balanced structures. an interesting characteristic of the new topology is the possibility of realizing lowpass, bandpass and highpass filters with a one‐to‐one relationship between the biquadratic parameters and the circuit elements. This characteristic allows the implementation of programmable switchable filters.
