Abstract
A new configuration for activating the symmetrical twin-T network to realise a medium-selectivity notch filter is given. The ω0 and Q factor sensitivities with respect to all circuit components are very low. The frequency-limitation equations for the circuit are derived, based on the 1-pole rolloff model of the operational amplifier.Keywords
