This letter introduces a novel phase detector (PD) for suppressing the reference spur in a 40 GHz integer-N phaselocked loop (PLL). Coined as a spur-compensation phase detector (SCPD), the proposed SCPD duplicates itself to an auxiliary path for an edge-combined phase alignment, such that the spurs...
