Abstract :
A new set of two interchange theorems is presented and proved which apply to current-mode analog circuits. These theorems can be applied to circuits which contain multiple current conveyors and current feedback operational amplifiers (CFOAs). The current conveyors can be either positive or negative. The circuits are modified by interchanging the input leads of a CFOA. The effects on transfer functions of the modified circuit are described by the new set of theorems. These theorems serve as useful tools in the design and analysis of linear, current-mode signal processing circuits
