Hi All,
I am using 55nM TSMC process. The 55nM has two I/O devices.
One is 2.5V device and another one is 3.3V device [2.5V over-drive].
Are those 3.3V devices good for analog design? For example can I design/tapeout a audio amplifier using them?
I am worried because they are not natural 3.3V devices[ these have same gate oxide as 2.5V] but these are tweaked to handle more voltage.
Does anyone have tapeout experience using these devices?
Are there any discrepancies between Models and silicon performance?

Thanks
SNIKE.
