PROJECT TITLE :

Simulating NBTI Degradation in Arbitrary Stressed Analog/ Mixed-Signal Environments

ABSTRACT:

A compact negative bias temperature instability (NBTI) model is presented by iteratively solving the RD equations during a easy means. The new compact model can handle arbitrary stress conditions while not solving time-consuming equations, and is hence, suitable for analogue/mixed-signal NBTI simulations in SPICE-like environments. The model has been implemented in Cadence ADE with Verilog-A and conjointly takes the stochastic impact of ageing into account. The simulation speed has increased at least a thousand times compared to classical RD models. The performance of the model has been validated by each RD theoretical solutions and one hundred forty-nm CMOS silicon measurement.
