Abstract In this work, a new design method has been developed for the low-pass filter (LPF) circuits by using the Nth Bernstein polynomials to meet the requirements on the flatness of pass-band and slope at the cut-off frequency. Almost all the methods utilized in the filter design are unified under a framework to obtain good results in both amplitude and phase respects. A simple but general synthesis method which is based on a new basic cell is given to simulate the circuits for controlling the realization of the designed filter on the basis of the requirements. Different type of filters which were not obtained since today are developed by this new method.
Key words: Bernstein polynomials, low pass filters, ladder filters, current conveyor.
