Abstract :
There is renewed interest in the use of non-Foster circuit elements in a variety of important applications such as wideband impedance matching and artificial magnetic conductors. Although non-Foster devices such as negative capacitors and negative inductors can be realized using current conveyors and Linvill circuits, a digital design approach may offer an important alternative in some applications. Therefore, digital discrete-time implementations of non-Foster circuit elements are investigated, and simulation results are presented for the implementation of a discrete-time negative inductor and a discrete-time negative capacitor.
