Abstract :
A lowpass continuous-time ΣΔ-modulator including FIR filters in the feedback path is presented. These filters allow for reduced sensitivity to clock jitter without affecting the ideal performance of the modulator. The FIR filters are conveniently implemented using the semi-digital approach.
