Active RC bandpass and lowpass filters using the d.v.c.c.s./d.v.c.v.s.

A novel configuration using the differential voltage-controlled current source, differential voltage-controlled voltage source (d.v.c.c.s./d.v.c.v.s.) as the active building block is introduced. The realisations of bandpass and lowpass filters are given as special cases; both filters are canonic, and a moderate pole Q-factor can be obtained in each case.
