1 Equivalent input bandwidth assumes a simple first-order input response and is calculated with the following formula: BWEQ = 0.22/(trCOMP2 – trIN2), where trIN is the 20/80
transition time of a quasi-Gaussian input edge applied to the comparator input and trCOMP is the effective transition time digitized by the comparator.
