A 2.56 GHz SEU Radiation Hard LC-tank VCO for High-speed Communication Links in 65 nm CMOS Technology

Journal Contribution - Journal Article

This paper presents a radiation tolerant Phase-Locked Loop (PLL) CMOS ASIC with an optimized Voltage Controlled Oscillator (VCO) for Single-Event Upsets (SEUs). The circuit is designed for high-energy particle physics experiments for low-jitter clock generation and clock recovery. An optimal tuning strategy of the VCO is presented that minimizes the cross-section and the SEU sensitivity of the oscillator. The circuit is processed in a 65 nm CMOS technology and has been irradiated with heavy ions with an LET (Linear Energy Transfer) between 10 to 69.2 MeV.cm²/mg. A comparison has been made with a conventional oscillator which proves a significant improvement in SEU sensitivity.
