Abstract A configuration using current feedback amplifiers has been presented, which is capable of realizing linear, positive/negative voltage‐controlled resistance, voltage‐controlled inductance and voltage‐controlled frequency‐dependent negative conductance in floating form (and thereby, also in grounded form) from the same structure. The workability of the proposed configuration has been demonstrated by hardware implementation results using AD 844‐type current feedback op‐amps (CFOAs) and BFW‐11‐type JFETs and the workability in high‐frequency range has been demonstrated by SPICE simulation using CMOS CFOAs.
