A design of passive negative shunt inductance circuit using negative group delay network

초록

A dispersive transmission line resonator can work in conj unction with a resistor, inductor and capacitor (RLC) circuit that can be configured to design a negative group delay (NGD) network. Furthermore, an NGD can be used as a non-Foster circuit (NFC), which can be implemented to enhance the bandwidth of some radio frequency (RF) modules. This paper discusses a dispersive short-circuit transmission line resonator as a NGD network that is used to design a passive negative shunt inductance circuit by controlling the dispersive medium of the transmission line resonator. The advantages of designing an inductance circuit this way are overcoming the power con- sumption problem of conventional NFCs and reducing the loss parameter caused by passive NFCs that was designed using RLC resonators.
