A dispersive transmission line resonator can work in conjunction 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 consumption problem of conventional NFCs and reducing the loss parameter caused by passive NFCs that was designed using RLC resonators.
