ABSTRACT:
A complex cascade sigma-delta modulator for analog-to-digital conversion applications. The modulator includes first and second sigma-delta modulator stages, combined with a complex digital noise cancellation circuit. In addition, analog-to-digital conversion of baseband signals using a complex sigma-delta modulator is also presented.
