Abstract :
The operational amplifier rolloff characteristics and a single capacitor are used for obtaining an inverting bandpass function. The filter performance depends on the gain-bandwidth product of the operational amplifier. Experimental results are included. The amplifier rolloff characteristics can be utilised in deriving transfer functions. The resulting filters have an extended frequency range of operation and a reduced number of external capacitors.
