Summary It is shown that the recently‐proposed modified current feedback operational amplifier (MCFOA) is quite a versatile element in that given a realization for a system function using MCFOAs, we can obtain three alternate realizations using the same MCFOA but by appropriately connecting the y , x , w , and z terminals of the MCFOA to the remaining part of the original realization. Using the results concerning the transpose of a multi‐terminal element, it is further shown that the transpose of an MCFOA is another MCFOA. Thus, using the results of transposition, given a voltage‐mode circuit using MCFOAs, we can directly obtain four current‐mode circuits using the same MCFOAs or vice versa.
