Perhaps you should try some spelling variations:
"raja ram cmos co" » "raja ravi cmos co", "raja m cmos co", "raja r cmos co", "raja from cmos co", "raja nm cmos co", "raja ram cmos cmos", "raja ram cmos ics", "raja ram cmos cdr"
"raja ram cmos rf" » "raja ravi cmos rf", "raja m cmos rf", "raja r cmos rf", "raja from cmos rf", "raja nm 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 co") 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 co\") or (((\"raja ram cmos rf\") OR (\"raja a cmos rf\"))))".
• Removing quotes may allow a broader search: (( raja ram cmos co ) or ((( raja ram cmos rf ) OR ( raja a cmos rf )))).
• Adding a wildcard symbol may retrieve word variants: (("raja ram cmos co") or ((("raja ram cmos rf") OR ("raja a cmos rf"))))*.
