Abstract :
The second-order effects of the gain-bandwidth product (g.b.w.) of operational amplifiers on the pole Q of certain active RC bandpass filters have been studied. These studies enable an accurate comparison of various configurations of active filters to determine their utility over a wide range of complex pole frequencies.
