Perhaps you should try some spelling variations:
raja from » raji from, trajan from, raja roy
from cmos » from amos, from cms, from cmds
cmos roy » cmos from, cmos rf, cmos co
ram cmos » a cmos, nm cmos, μm cmos
m cmos » nm cmos, _ cmos, a 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 from cmos roy ) OR ( raja ((ram cmos) OR (m cmos)) rf )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( raja from cmos roy ) or ( raja ((ram cmos) OR (m cmos)) rf ))".
• Adding a wildcard symbol may retrieve word variants: (( raja from cmos roy ) or ( raja ((ram cmos) OR (m cmos)) rf ))*.
