Is it legal to provide a copy of published IEEE paper on my personal website?
Yes, you can.

From https://www.ieee.org/documents/top10faq.pdf:


  Can an author post his IEEE copyrighted paper on his personal or
  institutions’ servers?  Yes. An author is permitted to post his IEEE
  copyrighted paper on his personal site and his  institution’s server,
  but only the accepted version of his paper, not the published version
  as  might be downloaded from IEEE Xplore.


Directly from their more recently updated paper policy (http://www.ieee.org/publications_standards/publications/rights/paperversionpolicy.html):


  The policy reaffirms the principle that authors are free to post the
  accepted version of their article on their personal Web sites or those
  of their employers. Posting of the final, published PDF continues to
  be prohibited, except for open access articles, whose authors may
  freely post the final version.
