A Power-Efficient Fractional-N DPLL With Phase Error Quantized in Fully Differential-Voltage Domain

Lianbo Wu, Thomas Burger, Philipp Schönle, Qiuting Huang

This article presents a power-efficient low-jitter fractional-N digital phase-locked loop (DPLL) that resolves phase error (PE) in the fully differential voltage (FDV) domain. Compared with adopting a traditional time-to-digital converter (TDC), which relies on gate delay in the time domain, power-efficient quantization …
