bin size

bin size jitter, FWHM, RMS, quantization error

In time-to-digital converters, the bin size is the unit of quantization for time measurements. In our TDCs other jitter sources are smaller than the quantization error. Therefore the measurement error for short intervals is dominated by the bin size in our devices. Under these circumstances, the maximum measurement error is close to half a bin. The rooted mean square (RMS) error is about 0.8 bins and the full width half maximum error is about 2 bins.
