All-digital oversampled front-end sensors

All digital signal processing (DSP) circuits use analog front-end anti-aliasing filters to process sensor inputs. These analog filters have a number of disadvantages with respect to cost, power, stability, and ease of integration in VLSI. This paper proposes the use of all-digital oversampling front...

description All digital signal processing (DSP) circuits use analog front-end anti-aliasing filters to process sensor inputs. These analog filters have a number of disadvantages with respect to cost, power, stability, and ease of integration in VLSI. This paper proposes the use of all-digital oversampling front-end sensors (based on adaptive filters), resulting in a performance/cost-effective DSP application. Simulations for modem and speech applications illustrate the design tradeoffs.
