Realizations of mutative 4-ports and their applications to memstor simulations

Abstract

In this paper, in addition to the universal 4-port mutator circuit introduced in [18] with an adder and a subtractor block, two more 4-Port mutator circuits, one with plus type (CCII+) and minus type current conveyors (CCII-), the other with a plus type current conveyor (CCII+) and one minus type current follower (CF-) are presented, their port relation matrix and their realization of different memstors are tabulated. How the transfer characterisitics of the ideal mutative 4-ports with respect to frequency hold is verified using their transistor level simulations. By terminating properly two ports of the mutative 4-port simulations of a memristor with three different mutators, of a meminductor and of a memcapacitor are presented and compared.
