Perhaps you should try some spelling variations:
"raja a cmos roy" » "raja a cmos from", "raja a cmos ram", "raja a cmos rp", "rajan a cmos roy", "rajah a cmos roy", "raja _ cmos roy"
"raja ram cmos co" » "raja ravi cmos co", "raja m cmos co", "raja r cmos co", "raja from cmos co", "raja μm cmos co", "raja ram cmos cmos", "raja ram cmos ics", "raja ram cmos dcs"
"raja ram cmos cdr" » "raja ravi cmos cdr", "raja m cmos cdr", "raja r cmos cdr", "raja from cmos cdr", "raja μm cmos cdr", "raja ram cmos cdba", "raja ram cmos adc", "raja ram cmos d"
"raja nm cmos rf" » "raja m cmos rf", "raja n 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 a cmos roy") OR ((("raja ram cmos co") OR ("raja ram cmos cdr"))))) OR ("raja nm cmos rf")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"raja a cmos roy\") or (((\"raja ram cmos co\") OR (\"raja ram cmos cdr\"))))) or (\"raja nm cmos rf\"))".
• Removing quotes may allow a broader search: (((( raja a cmos roy ) or ((( raja ram cmos co ) OR ( raja ram cmos cdr ))))) or ( raja nm cmos rf )).
• Adding a wildcard symbol may retrieve word variants: (((("raja a cmos roy") or ((("raja ram cmos co") OR ("raja ram cmos cdr"))))) or ("raja nm cmos rf"))*.
