  • Abstract
    The effect of finite gain bandwidth of nonideal operational amplifier on the performance of most of the second-order active filters is presented. The variation of the center frequency \\omega _0 and the quality factor Q of these filters due to the finite gain bandwidth is evaluated in detail. The usefulness of these filters for specific tolerances on \\omega _0 and Q are also pointed out.
