非福斯特电路元件的数字离散时间实现提供了传统模拟电路方法的替代方案。特别是，一个离散时间的负电容器的设计进行了研究，因为这样的非福斯特电路元件提供了显着的潜力，在宽带天线，超材料，和人工磁导体的应用。与模拟非福斯特电路一样，稳定性是数字非福斯特元件的重要设计考虑因素。因此，稳定性条件和仿真结果的离散时间负电容器，不稳定性的发病附近的预测稳定边界。
Digital discrete-time implementations of non-Foster circuit elements offer an alternative to conventional analog circuit approaches. In particular, the design of a discrete-time negative capacitor is investigated, since such non-Foster circuit elements offer significant potential in wideband antenna, metamaterial, and artificial magnetic conductor applications. As with analog non-Foster circuits, stability is an important design consideration for digital non-Foster elements. Therefore, stability conditions and simulation results are presented for a discrete-time negative capacitor, and the onset of instability is shown near the predicted stability boundary.
