Double-sampling allows to double the sampling frequency of a Σ∆ ADC without increasing the clock frequency. Unfortunately, path mismatch between the double-sampling branches causes noise folding, which ruins the performance. The fully-floating integrator is an interesting circuit to be used in such a double-sampling Σ∆ ADC because it is tolerant to path mismatch. However, this circuit exhibits ...

Abstract Reciprocity—the mutual provisioning of support/goods—is a pervasive feature social life. Directed networks provide way to examine the structure reciprocity in community. However, measuring involves assumptions about what relationships matter and how elicit them, which may impact observed reciprocity. In particular, practice aggregating multiple sources data on same relationship (e.g., ...
