Short answer: yes.
Longer answer: I believe the principles summarized by Calvin, usually known by the TULIP acronym, are biblical; I don't think he can be said to have come up with them, but rather that he drew his conclusions from scripture, and put them down in a compact form (in response to Arminian conlusions). Now, there is still a great deal of room about just exactly those principles mean, and no doubt there is room for difference between 'Calvinist' and 'Calvinist', and probably Calvin himself, lol - sometimes more than between 'Calvinist' and 'non-Calvinist', it seems
With due respect to Athanasian Creed above, I believe it is usually a matter of interpretation (of Calvin! not scripture!) that some passages seem in conflict with Calvin's TULIP principles. Of course, some may be a different understanding of scripture also; I hope AC did not mean to imply that the elect have something to boast about in their salvation (by using untainted will to repent, for example ?) - but his comment could be taken that way; even so Calvin's principles have been twisted at times, far beyond what I think is reasonable
