Abstract:
A method for digitizing an analog signal through a pipelined analog-to-digital converter (ADC) may include pipelining a sample sub-stage, a quantization sub-stage and an amplification sub-stage to an ADC lane. Within a first of multiple pipelined stages, clock phases may be assigned to the ADC lane, including a sample clock phase, a quantization clock phase, and an amplification clock phase such that the quantization clock phase is non-overlapping with the sample clock phase and the amplification clock phase. The non-overlapping feature may be facilitated by generating multiple reference clock phases for the sub-stages of multiple ADC lanes, and interleaving assignment of the sample clock phase, the quantization clock phase, and the amplification clock phase to the reference clock phases among the multiple lanes.
