Abstract :
This contribution is focused on comparison of two minimal configuration solutions of single-input triple-output (SITO) current-mode filters, which are using only multiple-output current followers (MO-CF) are active elements. Both filters are universal, have fixed topology and do not provide electronic tuning possibility directly from proposed structure. Advantages and also disadvantages of both solutions are discussed and features are confirmed by simulation with simple BJT-based model of current follower.
