The updated ferroelectric model is invoked in\u00a0SmartSpice<\/i><\/b>\u00a0by setting LEVEL=6 in the capacitance model card. This model differs from its predecessor (model FCAP LEVEL=5) in that the ferroelectric capacitor is regarded as a non-linear capacitor with Polarization-Voltage (P-V) hysteresis loop, however the biases in the ferroelectric materials are reversed at reversal voltages with double distributions. As compared with the LEVEL=5 model, the LEVEL=6 model demonstrates the following improvements: more accurate simulations of ferroelectric hysteresis loops and sub-loops, improved voltage pulse responses, faster simulation speed (up to six times faster), and added temperature dependence.<\/p>\n
