Abstract:
High-speed radiation-hardened frequency synthesizers are a key block in spaceborne communications systems. This article presents a 15–22-GHz radiation-hardened phase-locked loop (PLL) designed in a 22-nm FinFET process with hardening techniques for single-event upset (SEU) and total ionizing dose (TID) implemented in all key PLL blocks. Electrical performance tradeoffs arising from …
