Abstract

A low component sensitivity band-pass filter has been proposed. The filter has only one operational amplifier as active component and three resistors and one grounded capacitor as passive components. Two resistors provide the positive feedback and one resistor is used for independent tuning of Q factor. The capacitor is grounded which is an advantage in integrated technology. The circuit uses the pole frequency of the operational amplifier for its working and can be operated at high frequency range. PSpice simulations have been presented to verify theoretical analysis.
