放射線耐性をもつPLL回路
Radiation-Hardened PLL
概要
PLLs in digital circuits are source of the clock signal. Perturbation on PLLs is crucial because change or lack of clock signal leads whole system malfunction. Radiation-strike is considered as one of the causes of PLL malfunctioning. Thus, importance of radiationhardened PLL is increasing. In this work, we have proposed a radiation-hardened PLL (RHPLL) which mitigate penalties in silicon area and power consumption. Following figure shows comparison of three types of PLLs in silicon area, power consumption and jitter of radiation-strike condition.
産業界への展開例・適用分野
The proposed RHPLL is mainly required for space applications such as space shuttles, satellites because radiation level is high at over airplain altitude. Not only space applications but also high reliability digital circuits/systems that operate at ground level needs the proposed RHPLL to satisfy severe error-standard.
