0.18um supply voltage
Dear all, I am now confused by the supply voltage of IC. It seems to be related to the process. For example, the TSMC 0.18um tends to use both 3.3V and 1.8V, and 0.25um process tends to use 2.5V, while 0.6um or so use 5V. But, why it is 5V rather than 4.5V, why it is 3.3V rather than 3V? Are there any reference standard?
Would any one of you please enlight me on this topic? Thank you all in advance.
