A Radiation-Hardened 15–22-GHz Frequency Synthesizer in 22-nm FinFET
A Radiation-Hardened 15–22-GHz Frequency Synthesizer in 22-nm FinFET 150 150
Author(s): David Dolt, Samuel Palermo

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 …

Abstract:

This work presents a power-efficient level crossing (LC) ADC designed to digitize sparse signals. It uses dynamically self-biased comparators, which require minimal current when the input voltage is far from a decision threshold. It also uses a DAC architecture which avoids the signal attenuation commonly present in prior LC ADC …
