There is an invisible enemy that constantly threatens the operation of electronics: ionizing
radiation. From sea level to outer space, ionizing radiation is virtually everywhere. At sea …

In this work, a comparison has been made between a low noise ring-oscillator and an LC-
oscillator Phase Locked Loop (PLL). An ASIC has been developed to conduct irradiation …

A voltage-controlled oscillator (VCO) is one of the key modules of the phase-locked loop
(PLL) microsystem, and it is easy to bombard using high-energy particles in a radiation …

The design of a Phase-Locked Loop (PLL) to generate the clock reference for the new
Spacefibre standard is presented in this paper. Spacefibre has been recently released by …

This paper presents a radiation-hardened-by-design (RHBD) phase-locked loop (PLL)
which utilizes a feedback voltage controlled oscillator (FBVCO) to mitigate a single event …

Single event upset (SEU) is a significant problem in analog, digital, and mixed signal
circuits. The extent of the attacks increases in radiation susceptible environments such as …

A radiation-hardened-by-design (RHBD) current-starved-ring voltage-controlled oscillator
(CSR-VCO) design is proposed based on the separation of gate input technique to mitigate …

Advanced CMOS technologies have demonstrated reduced sensitivity to radiation total-
ionization-dose (TID) effect. However, the reduced device dimensions can significantly …

A single-event-transient-hardened-by-design (SET-HBD) charge pump (CP) is proposed to
improve the reliability of the phase-locked loop (PLL) in SMIC 0.18 μm CMOS process. And …

Electronic circuits operating in the radiation intensive environment like space, are subject to
a barrage of cosmic particles like neutrons, protons, and heavy ions which can cause …
