  • Spread spectrum chopping for sigma delta modulators
    Patent number: 11967972
    Abstract: Chopping techniques that suppress fold-back into the signal band and spreads the offset across the spectrum are described. By using various techniques, chopping may be performed with a variable frequency clock to spread the offset across the signal spectrum. Spreading the offset across the signal spectrum means that there are no longer large spurious tones at a few frequencies.
    Type: Grant
