High-Integrity Data Converters: Bridging Analog and Digital in Radiation-Prone Missions
A rad-hard by design Time-to-Digital Converter is presented with a single-shot precision of 8 ps and a zero dead zone measurement range of 0 ps up to 3s. The analog and digital building blocks and the overall chip architecture are developed for radiation performance, to support time of flight and time tagging applications in space.
In space-related projects, radiation effects such as Total Ionizing Dose (TID) effects and Single Event Effects (SEEs) are the main threat to the microelectronic conponents. ADCs, which are the crucial components of the telecommunication chain, are also facing these challenges. Radiation hardening is mandatory for the assurance of function and performance for ADC, which usually brings...
This paper presents a compact, high-speed 10-bit wideband data converter for direct conversion of the microwave spectrum up to 40 GHz (Ka-band). With a 33 GHz input bandwidth, it supports RF direct sampling at 12.8 GSps with only 2.5W power consumption, eliminating the need for external mixers and simplifying system design. NPR performance has been measured up to 40 GHz, making it ideal for...
This paper presents the design, implementation, and experimental validation of a 14-bit 80 MS/s calibration-free radiation-hardened pipeline analog-to-digital converter (ADC) realized in 28-nm bulk-CMOS technology. The escalating demand for high-performance ADCs in radiation-rich environments necessitates robust designs capable of withstanding ionizing radiation-induced errors without...
