Abstract: An adaptive digital loop filter (DLF) for fast-locking TDC-based all-digital phase-locked loop (ADPLL) is proposed. The proposed DLF utilizes a proportional-integral filter structure with ...

Abstract: This article proposes a radiation-tolerant phase-locked loop (PLL) for space-based applications. The proportional and integral path is proposed to mitigate the single-event effects (SEEs) ...
