It depends on the frequency range. The most known methode is using a voltage controlled OA. Example: BA6110 (obsolete). http://www.datasheetcatalog.net/cgi-bin/helo.pl?field=Nume&type=C&text=BA6110&producedby= For high frequency there is a different approach. Who knows a few methodes ?

Now I need to tune the R and C of this filter since the variation of these components are 20% in the silicon..I am looking for any proven method for this.. Thank you..
