Abstract :
In this paper a capacitor less bandpass filter has been reported. The filter uses two operational amplifiers as active components both in feedback mode. The circuit utilizes the pole of both operational amplifier to realize bandpass transfer function and can be operated at high frequency range. The elimination of capacitor makes it suitable for integration. PSPICE simulation has been presented to verify theoretical analysis.
