STF behaviour in a CT ΔΣ modulator


In this paper we propose a topology for continuous time SigmaDelta modulators. Unlike the modulators presented until now, they exhibit no peaking in their signal transfer function. Instead it achieves a 'flat' STF with the desired anti-aliasing properties and with small internal nodes signal levels. Now, a simple filter, e.g. a first-order low-pass filter… (More)
