CMOS ring oscillator frequency degradation through years
Hi
I am ruining simulation in VIrtuoso-Cadence, with 13 stage RO (22nm technology) and I am getting a weird frequency degradations. In the 1st case, I am runing the simulation using the tool ADE-L and it shows a 6% degradation in 10 years of aging. The 2nd case, I am using the tool ADE-XL and it is showing a frequency degrdation of 22% in 10 years of aging. What do you think should be the right number on this? Both of them are beign stress in a temperature of 25 Celsius. Please suggest me any recent papers on this, or books.
