Abstract :
A simple method is proposed to measure the large signal permittivity and loss tangent of ferroelectric films. Measured, at zero DC bias, large signal dielectric properfies are used to develop scaleable large signal circuit models of ferroelectric varactors. The model is useful for zero bias mixer (up and downconverter) and harmonic generator applications of ferroelectric varactors.
