Perhaps you should try some spelling variations:
cmos from » mmos from, cosmos from, bicmos from
raja ram » raja ravi, raja r, raja roy
ram cmos » from cmos, nm cmos, μm cmos
raja m » raja _, raja j, raja r
m cmos » nm cmos, _ cmos
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 ram cmos from ) OR ((( raja m cmos from ) OR ( raja a cmos from )))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( raja ram cmos from ) or ((( raja m cmos from ) OR ( raja a cmos from ))))".
• Adding a wildcard symbol may retrieve word variants: (( raja ram cmos from ) or ((( raja m cmos from ) OR ( raja a cmos from ))))*.
