Abstract
A signal adaptive control architecture for a second-order ΔΣ modulator design is presented. This architecture effectively reduces the power dissipation and the distortion of the first stage in the modulator. The function of this architecture is to switch off the DAC feedback signal to the first stage during some iterations, and to compensate the signal at the second stage, in an adaptive manner
