Effective Resolution of an Adaptive Rate ADC

Résumé

Most real life signals are of non-stationary nature. An efficient acquisition of such signals can be achieved by adapting the acquisition rate according to the input signal local characteristics. In this context, an ARADC (Adaptive Rate Analog to Digital Converter), based on the level crossing sampling is proposed. The ADC effective resolution is a classical parameter to characterize its performance. In this context, a novel method is devised to measure the ARADC resolution. A criterion for properly choosing the different system parameters in the aim of acquiring the desired effective resolution is also described.
