摘要

为改善天线增益-带宽权衡关系的限制，负阻抗变换器(NIC)受到了广泛关注。然而，NIC的一个重要问题是由于正反馈的存在而导致不必要的振荡的潜在不稳定性。为了解决这一问题，我们提出了一种稳定且具有负阻抗宽带特性的NIC电路技术。

Stability analysis of negative impedance converter

Negative Impedance Converter (NIC) have received much attention to improve the restriction of antenna gain-bandwidth tradeoff relationship. However, a significant problem with NIC is the potential instability of unwanted oscillation due to the presence of positive feedback. For solving this problem, we propose a NIC circuit technique which is stable and has wideband characteristics of negative impedance.
