Abstract
Active RC circuits with arbitrary transfer characteristics in current mode are presented in this paper. The given circuits are based on the multiple-loop feedback structure, namely on the follow-the-leader feedback structure with output summation. Modeling by signal flow graph technique is used to modify and transform the structure in current mode. Implementations by multi-output current-differencing-input transconductors (CDTA) are given. Verification and illustration are shown. The designed circuits have been simulated in PSpice and SNAP, resulting responses are confirming the theoretical assumptions.
