An analytical model to evaluate the hybrid architecture of a wide bandwidth high-speed digitizer is proposed. The model is based on the robust approach of multi-rate signal processing theory and allows analyzing the effects of the impairments that can affect the digitizer, and consequently evaluating achievable performance. The proposed model can also be used at design stage to identify viable solutions for counteracting the effects of the impairments. More specifically, it can be used to identify the correction filters that provide a digital representation of the input signal that minimizes spurious terms and distortions.

Abstract
An analytical model to evaluate the hybrid architecture of a wide bandwidth high-speed digitizer is proposed. The model is based on the robust approach of multi-rate signal processing theory and allows analyzing the effects of the impairments that can affect the digitizer, and consequently evaluating achievable performance. The proposed model can also be used at design stage to identify viable solutions for counteracting the effects of the impairments. More specifically, it can be used to identify the correction filters that provide a digital representation of the input signal that minimizes spurious terms and distortions.| File | Dimensione | Formato | |
