Abstract :
The general analysis of a ferroelectric-based nonlinear transmission line (NLTL) is presented. Analysis allows the estimation of the efficiency of NLTL meant for increasing the wave steepness under propagating along NLTL. Figure of merit defined as the relative change of the reciprocal steepness of the wave front at NLTL input and output is suggested to characterize the NLTL efficiency. Formulas allowing the calculation of figure of merit for ferroelectric-based distributed NLTLs and lumped element networks are derived with the use of a phenomenological description of capacitance-volt age dependencies of ferroelectric (FE) capacitive elements of NLTLs
