Abstract
A circuit network with a pair of operational amplifiers and impedance elements, to show equivalent impedance, between two network terminals, of a value either well reduced or enlarged from the impedance of the impedance elements. The network may thus function as idealized diode when the impedance elements are diodes, or may be of large equivalent capacitance or inductance, as the impedance elements are capacitors or inductors.
