Total Ionizing Dose Effects in Phase-Locked Loop ICs and Frequency Synthesizers

This paper presents a brief overview of total ionizing dose effects for a variety of PLL ICs and PLL-based frequency synthesizer implemented in commercial bulk CMOS, silicon-on-insulator CMOS, BiCMOS and SiGe BiCMOS technology processes with frequency range up to 8 GHz. Total dose sensitivity data of PLL ICs have been obtained at the SPELS test center, based on comprehensive parametric and functional control.
