The performance of continuous-time (CT) DeltaSigma modulators is limited by their sensitivity to clock phase noise (PN). The clock PN-induced in-band noise (IBN) is dependent on the magnitude and frequency of both the desired in-band signals and the out-of-band signals, as well as the shape of the clock PN spectrum. This brief presents a discrete-time (DT) model of the dominant clock PN-induced er... View full abstract»
