[SOLVED] What are the lengths and widths of 45nm technology

[prashanth7457]

I want to know what are the lengths and widths of 45nm technology.

In what ratio the PMOS and NMOS should be. How can we find out whether the transistors are 45nm or 90 nm or 180nm

And is it necessary the lengths of PMOS and NMOS should be same

To the best of my knowledge ,45nm technology means gate length will be 45nm.And W/L ratios depends on how you have designed circuits and what bias currents you want.For example in cadence virtuoso,I am using gpdk180 library which means,I am using 180nm technology so my L=180nm.And depending on my design,current mirrors ,I have designed W/L ratios.

Below is a link that goes into process naming. I am sure there are others on the internet that are a bit more clear.

Until you get to ~45nm the technology is still named after the transistor size. Below that it gets very ugly.
