Perhaps you should try some spelling variations:
cmos from » mmos from, cosmos from, bicmos from
raja ram » raja ravi, raja m, raja r
ram cmos » from cmos, m cmos, μm cmos
raja nm » raja m, raja n
raja a » rajan a, rajah a, raja _
a cmos » _ cmos

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (((( raja a cmos from ) OR ( raja ram cmos ics ))) OR ( raja nm cmos rf )).
• Adding a wildcard symbol may retrieve word variants: (((( raja a cmos from ) or ( raja ram cmos ics ))) or ( raja nm cmos rf ))*.
