Abstract :
The problem of designing analog N-path filters which are time-invariant and which exhibit single-band or multiband frequency responses is addressed. Specifically, the authors devise design procedures that give the required number of paths and the corresponding period of the modulating functions. The resulting number of paths is no larger (usually smaller, sometimes significantly smaller) than those obtained by existing methods
