Hello there.
The circuit in the pic is used in receiving stage of an RFID reader. All I know is that the first two filters are active twin-t filters and the third one is a butterworth low pass filter.
Can someone confirm this. Also I need the design procedure for the same. Please help...![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
