【 摘 要 】
Non-Foster circuits (NFC), in conjunction with the effect of negative impedance, have been applied to design broadband radio frequencies (RF) due to their wideband impedance matching ability. There are many approaches to designing non-Foster circuits that use transistors with loops inside to obtain negative reactance. Hence, conventional NFC has some problems, including complex connectivity and power consumption. In this paper, we analyse other properties of NFC phase and group delay, and we realize that these properties are related to properties of negative group delay (NGD) networks. Therefore, we proposed a new design of passive non-Foster circuits, that is less complicated and does not require power.
