Contribution to ageing simulation of complex analogue circuit using VHDL-AMS behavioural modelling language

摘要

This paper presents a method to upgrade ageing simulations of analogue ICs. An Operational Transconductance Amplifier (OTA) is analysed by electrical simulation on order to define its electrical ageing behavioural model Including electrical stress dependency. The ageing part of the behavioural model is built using transistor level Electrical simulations of the OTA and a transistor ageing model.
