Implementation of N-Path Filters Using Two-Level Modulation.
Abstract
Recently, renewed interest has been given to the use of N-path filters as an alternative method of realizing analog filters. The N-path filter is a configuration composed of N-parallel paths containing identical path filters flanked by input and output modulators. The design of an N-path filter requires that its periodic modulating functions provide a desired set of Fourier coefficients while the rest of the Fourier coefficients may be arbitrary. To illustrate this numerical method, three applications of the N-path filter that are of practical interest are considered: A single passband filter; A least mean-squared error filter; A filter matched to a periodic input signal.
