I think that the University of Bedfordshire should have more books related on Engineering course. Also as in a electronic source and hardcopies as well. IEEE - electronic source. Electronic devices and circuits
I have done a very crude search on the library catalogue for materials for your course and found around 100 items. This includes print (hardcopy) and digital items. A proper search would undoubtedly reveal more. I can reassure you that IEEE is part of the University's digital collection.
Please remember the catalogue and DISCOVER search boxes are on the front page of LRWeb

I am concerned that you may need some assistance with your search strategy. I would advise you to contact your Academic Liaison Librarian to discuss your particular requirements

May I also remind you that if an item is not at your home Campus you may use the reservation service to ensure that you have access to the required title

Your librarian has created a raft of information for your course and you may find this helpful too
