Oversampling analog/digital converter with noise shaping in switched capacitor techniques

摘要

u00fcberabtastender analog to digital converter with at least three, each with an analog input signal (vin) controlled and both an analog and a digital output (voa, vod, q) receiving identical in switched - capacitor technology and built umsetzerstufen (u1, u2, u3), d the umsetzerstufen em (u1, u2, u3) on the analog input and output signals (vin,voa) are connected in series, and in which the digital output signals (vod) umsetzerstufen (u1, u2, u3) on each of a number of series connected differenzierstufen (v1, v2, a2, a3), which is equal to the number of the upstream umsetzerstufe (u1, u2) is conducted and aufsummie rt rt rt rt rt rt rt.
