An Immitance Based Tool for Modelling Passive One-Port Devices by Means of Darlington Equivalents

Immitance data modelling via linear interpolation techniques: A classical circuit theory approach

“…If suitable, one may as well utilize a pole location estimation procedure, which is described in Reference [16].…”

Real frequency techniques to design ultra wideband circuits

“…In these years, SRFT had also been employed to model measured data obtained from active and passive devices [41][42][43][44][45]. Recently, utilizing SRFT, we have completed several designs of multi-band antenna matching and switch networks for cellular communication systems [26][27][28].…”

“…Therefore, it is suitable to design antenna matching networks, as well as microwave amplifiers . When it is combined with modeling techniques [41][42][43][44][45], it yields outstanding solutions to any kind of matching problems. It should be mentioned that all the real frequency techniques are gathered in recently published books [52][53] …”

Gain-sensitivity analysis for cascaded two-ports and application to distributed-parameter amplifiers

“…One considerable application for cascaded two-ports is the synthesis of microwave amplifiers using lumped and/or distributed elements. In particular, after solving the problem of definite target space [8], a cascaded configuration is very easy to use in the design with together the Darlington representation of the source and load impedances [9]. Designing a microwave amplifier using the potential-noise, input-VSWR, and gain performances, with predetermined bandwidth for the employed active device, can be considered as a significant development in current state-of-the-art microwave technology.…”
