Abstract

A triangular window is introduced in the traditional zero crossing (ZC) counting frequency to digital converter (FDC) to achieved a Δ-Σ noise-shaping and decimation results. A simple way to implement the windowing function is by using a double modulo counter or a sinc2 decimator. A higher digital resolution can be achieved by using a Δ-Σ decimator as a ZC counting FDC than by using a standard count-and-dump FDC as the quantization error is noise-shaped.
