Continuous-time digital filtering analogue-to-digital converter

Abstract : Despite their alias-free operation, continuous time ADCs can have their power consumption overwhelmed when presented out-of-band, high frequency, high amplitude signals. A new continuous time ADC architecture which, thanks to its embedded low-pass filter transfer function is proposed, enables a power efficient quantisation in the presence of such signals. Moreover, the half-digital nature of this approach simplifies the implementation of the proposed system compared to a standard filter-first solution.
