Perhaps you should try some spelling variations:
"raja from cmos from" » "raja from amos from", "raja from cms from", "raja from cmds from", "raji from cmos from", "trajan from cmos from", "raja roy cmos from", "raja from mmos from", "raja from cosmos from", "raja from bicmos from"
"raja ram cmos roy" » "raja ravi cmos roy", "raja m cmos roy", "raja r cmos roy", "raja nm cmos roy", "raja μm cmos roy", "raja ram cmos co", "raja ram cmos ram", "raja ram cmos rp"
"raja ram cmos rf" » "raja ravi cmos rf", "raja m cmos rf", "raja r cmos rf", "raja nm cmos rf", "raja μm cmos rf"
"raja a cmos rf" » "rajan a cmos rf", "rajah a cmos rf", "raja _ cmos rf"

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 roy") OR ("raja from cmos from"))) OR ((("raja ram cmos rf") OR ("raja a cmos rf")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"raja ram cmos roy\") or (\"raja from cmos from\"))) or (((\"raja ram cmos rf\") OR (\"raja a cmos rf\"))))".
• Removing quotes may allow a broader search: (((( raja ram cmos roy ) or ( raja from cmos from ))) or ((( raja ram cmos rf ) OR ( raja a cmos rf )))).
• Adding a wildcard symbol may retrieve word variants: (((("raja ram cmos roy") or ("raja from cmos from"))) or ((("raja ram cmos rf") OR ("raja a cmos rf"))))*.
