Abstract
A semi-empirical CAD model of ferroelectric capacitor for circuit simu lation as well as for device characterization is proposed. The model c an successfully describe the followings with only 5 parameters(V-c, V- o, P-s, C-o, tau) which have definite meanings. These are 1) hysteresi s of charge vs. voltage (Q-V) relationship and capacitance vs. voltage (C-V) relationship, including partial polarization switching by minor voltage sweep. 2) characteristic time dependent polarization reversal (switching) current.
