This paper analyzes the effects of radio frequency interference on second order ΔΣ modulators based on continuoustime (CT) and on discrete-time (DT) architectures. Specifically, Modulators used for the acquisition of sensor signals are targeted, which can operate with moderate clock rates due to the relatively small bandwidth of the signal to be acquired. A continuous wave interference with frequency above that of the modulator clock signal is superimposed onto the nominal input one with the purpose of evaluating the degradation of their performance, and more specifically their capability to demodulate out of band interference.

Abstract
This paper analyzes the effects of radio frequency interference on second order ΔΣ modulators based on continuoustime (CT) and on discrete-time (DT) architectures. Specifically, Modulators used for the acquisition of sensor signals are targeted, which can operate with moderate clock rates due to the relatively small bandwidth of the signal to be acquired. A continuous wave interference with frequency above that of the modulator clock signal is superimposed onto the nominal input one with the purpose of evaluating the degradation of their performance, and more specifically their capability to demodulate out of band interference.File | Dimensione | Formato | |
