A Digital PLL Using Oversampling Delta-Sigma TDC

Abstract

A digital phase-locked loop (DPLL) using a delta-sigma time-to-digital converter (ΔΣTDC) is presented. This ΔΣTDC adopts the oversampling and feedforward techniques to improve the phase noise of the DPLL. The DPLL is fabricated in a 40-nm CMOS process. The proposed ΔΣTDC consumes 0.519 mW at a supply of 1.1 V, and… (More)
