WebThe CIFF improves the performance of CIFB in terms of the signals at the output of the integrators. As can be seen from Eq. (7), the signal at the output of the first opamp contains a first-order noise shaped input-signal component in addition to shaped quantization noise. This reduces signal swing and reduces dependence of the distortion
