WebNov 1, 2024 · An ultra-low power dynamic comparator is proposed with dynamic offset cancellation in this Letter. The dynamic offset voltage can achieve <0.5 LSB when common-mode voltage varies from 0.5V DD to V DD with the cascode current source for 10-bit SAR ADCs. The power consumption can be ultra-low since it has no power … WebOct 17, 2024 · Figure 2 shows two popular DOC methods: AZ and chopping. AZ is a sampling-based method used to remove the input end offset of an op amp. As shown in Figure 2a, the AZ is controlled by clocks P 1 and P 2, which are the offset sampling and amplifying phases, respectively.By storing the offset in the offset sampling capacitor (C …
