Abstract
The influence of the finite gain bandwidth-product of operational amplifiers on the centre frequency and quality factor of the dominant pole of resistively symmetric MOSFET-C filters is presented. It is proved that the capacitor connection for which the structure of the filter is resistively and capacitively symmetric minimises the influence of the gain bandwidth-product on the centre frequency and quality factor parameters of the pole.
