Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Conference Paper Description
The input feedforward path in a ΔΣ modulator is an attractive technique for low-distortion swing-reduction design. It helps lower the power dissipation, especially in ΔΣ modulators designed with low oversampling ratios (OSRs) in low-voltage nanometer CMOS technologies. However, a ΔΣ modulator with analog feedforward (AFF) requires an analog adder before the quantizer, which can limit the achievable resolution or degrade the signal swing and increase the power dissipation. In this paper, a single-stage multibit ΔΣ modulator with digital feedforward (DFF) is proposed to realize a high-order finite-impulse-response noise transfer function, thereby achieving high signal-to-quantization-noise ratios at low OSRs. Its key features include reduced swing at the opamp outputs, reduced sensitivity to integrator nonlinearities, and robustness to ΔΣ modulator coefficient variations, all of which, are achieved using only minimal additional digital hardware. Behavioral simulation results confirm that the proposed DFF modulator achieves the swing-reduction and low-distortion performance of an AFF modulator, while eliminating the need for an analog adder. © 2008 IEEE.
