Advertise your A/D converter, a SP teaching strategy
(2010-03) Saint-Nom, Roxana
"The goal of this paper is to invite the reader to consider role-playing as a method to train Signal Processing students for professional functions they would undertake in their future careers. Interaction, communication skills and learning purposes of SP concepts are key elements of this approach. An example applied to Analog to Digital converters is detailed, to show the advantages of this technique and the enthusiasm awakened."
A chopped front-end system with common-mode feedback for real time ECG applications
(2017) Gardella, Pablo; Villa Fernández, Emanuel; Baez, Eduardo; Cesaretti, Juan Manuel
"A Front-End system composed of an instrumentation amplifier with common-mode feedback and a second-order sigma-delta analog to digital converter is proposed. Chopping techniques are used to remove offset and low frequency noise to guarantee a noise floor below the signal of interest. Measurements show that common-mode feedback adds 71 dB to the CMRR at 50 Hz and the input referred noise is 1.17 μVRMS over the frequency range of 0.1 Hz to 400 Hz."
