Systems and methods for providing anti-aliasing in a sample-and-hold circuit

摘要

Systems and methods are included for providing anti-aliasing in a sample-and-hold circuit. One embodiment of the present invention includes a method for sampling of an input signal for providing to an analog-to-digital converter. The method comprises generating a sample signal having a given frequency and a period that defines both a sample phase and a hold phase. The method also comprises sampling the input signal at both the sample phase and the hold phase. The method further comprises generating a decimated output sample that is an aggregate of consecutive samples of the input signal obtained during the sample phase and the hold phase.
