Perhaps you should try some spelling variations:
cmos from » mmos from, cosmos from, bicmos from
raja ram » raja ravi, raja m, raja roy
ram cmos » from cmos, m cmos, μm cmos
raja nm » raja m, raja n
raja r » raja _, raja j, raja m
r cmos » _ cmos, m cmos, 4 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 nm cmos from ))) OR ((( raja r 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 nm cmos from ))) or ((( raja r cmos from ) or ( raja a cmos from ))))".
• Adding a wildcard symbol may retrieve word variants: (((( raja ram cmos from ) OR ( raja nm cmos from ))) or ((( raja r cmos from ) or ( raja a cmos from ))))*.
