Abstract
Analog-to-digital converter (ADC) output bits are partitioned in a way that simplifies the phase error calculations. The circuit architecture embeds the implementation of the phase error calculations in the analog-to digital-converter (ADC) to simplify the overall circuit implementation. Simplification of the phase error calculations allows a reduction in the complexity of the circuits needed to implement the phase-locked-loop (PLL) for recovering the sampling clock.
