摘要：
Analog-to-Digital Converter (ADC) based Serializer- Deserializer (SerDes) receivers perform down-sampling in analog domain to address the speed limitation of the ADCs. This paper presents an analysis of the impact of down-sampling on nonlinearity of the analog data path. The nonlinearity is derived to quantify the contribution of down-sampled and non-down-sampled paths. The effect of bandwidth of down-sampled path on nonlinearity is analyzed. Nonlinearity estimators are proposed to distinguish between down-sampled and non-down-sampled path nonlinearity in real time receiver operation. The proposed analysis is applied to a 50 Gbps ADC based receiver.
