A method for generating some active circuits

A novel technique is used to derive networks termed converter-inverter circuits. These are 5-ports that can be used to produce any of the following four basic circuits encountered in active network theory: positive impedance converters, negative impedance converters, positive impedance inverters, and negative impedance inverters. Thus a converter-inverter circuit is a very general network; this generality of the circuit demonstrates that the new technique is very versatile.
