The concept of an All Digital Phase Locked Loop (ADPLL) with an up-down counter is conceived and presented here. The phase error of a Phase Detector (PD) in a Digital PLL is delivered in bits.

Neuchâtel, Switzerland-based Aktiia said its G0 Blood Pressure Monitoring System will be available in the U.S. in 2026.

This paper presents a high-resolution, high-lineartity, two-step Time-to-Digital Converter(TDC) for wideband counter-assisted ADPLL. The proposed design uses two-step conversion scheme with buffer ...
