Abstract :
This paper presents a high-speed floating-point analog-to-digital converter in the framework of deterministic signal acquisition systems. The proposed circuit allows quantization of large dynamics signals, while keeping a low relative error. FP-ADC precision characteristics are analyzed in the context of exponential decay signals acquisition.
