The signal transfer function (STF) of a continuous-time delta sigma modulator (CTDSM) has traditionally been determined using frequency-domain arguments. Unfortunately, the signal flow manipulations used in this process are not valid when the loop filter is periodically time varying, as in the case of modulators with switched-capacitor (SC) or return-to… (More)
