SMASH ΔΣ modulator with adderless feed-forward loop filter
(Wiley-Blackwell, 2017)
A novel cascade ΔΣ modulator, which combines the benefits of sturdy MASH (SMASH) topology and feed-forward loop filter, is presented. The proposed ΔΣ architecture is based on moving the power-hungry adder block from the ...
