人们对在宽带阻抗匹配和人造磁导体等各种重要应用中使用非福斯特电路元件重新产生了兴趣。尽管负电容器和负电感器等非福斯特器件可以使用电流传输器和 Linvill 电路来实现，但数字设计方法可能在某些应用中提供重要的替代方案。因此，研究了非福斯特电路元件的数字离散时间实现，并给出了离散时间负电感器和离散时间负电容器的实现的仿真结果。
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.
