Filter Hardware Cost Reduction by Means of Error Feedback


The article presents an uncommon application of the error feedback-improved IIR filter. A simple method to reduce the hardware cost (silicon area) of the biquadratic section implementation by means of error feedback (EF) is described. The optimization method utilizes the fact that the filter with an EF is more resistant to roundoff noise than a filter… (More)
