The TWINTOR in bandstop switched-capacitor ladder filter realization

A design for strays-insensitive bandstop switched-capacitor ladder filter structures is introduced. A two-channel scheme obviates the need for term cancellation in realizing bandstop-type operators. A major feature of the circuit is that the clock period required is 2T, so that the circuit can operate at a higher speed without extra demands on op amp performance.<
