SIGMA-DELTA MODULATOR APPARATUS AND METHOD OF GENERATING A MODULATED OUTPUT SIGNAL |
摘要 |
A discrete time sigma-delta modulator apparatus for class-D operation comprises a feed-forward path having an input at one end thereof and an output at another end thereof. A first summation unit is coupled in the feed-forward path to a first integrator. A quantizer is coupled in the feed-forward path after the first integrator and a feedback path arrangement is coupled to an input of the first summation unit. A low pass filter is arranged in the feedback path arrangement so as only to drive the first integrator.
