摘要: The conditions under which an active device exhibits input impedance at one terminal pair is exactly the negative of load connected to other are discussed. There infinite number ways by such a device, called negative-impedance converter (NIC), can be made. One limits this set represented transistor circuit was discussed previously Linvill; limit, new introduced recently. Practical converters not exact; however, they may made so addition compensating impedances. parameters NIC most affect performance indicated as guide design. Two typical circuits compared on basis. Experimental results given.
