Abstract :
Nth-order synthetic elements are presented in this contribution. Two basic current-mode dual-output active elements known as dual-output current followers (DO-CF) are used in the essential single-ended (S-E) circuit and two fully-differential current followers (FD-CF) are used in the fully-differential (F-D) equivalent. Both S-E and F-D 2nd-order low-pass and high-pass responses are shown as examples of particular solutions. Results of AC simulations together with tolerance analyses are included in order to prove design correctness.
