Abstract

The influence of the oxide hard breakdown (HBD) path location along the channel in nMOSFETS on the performance and power consumption of a five stages ring oscillator has been evaluated. A simple MOSFET transistor model which takes into account the oxide BD has been used to do the analysis. The results show that in some cases, after oxide BD, the ring oscillator still operates but the circuit could fail due to higher consumption.
