The design minimizes transistor count, substitutes inductors for transistors where possible, uses physically enlarged NMOS transistors instead of PMOS, and reduces parallel segments to limit radiation-induced damage. After successive exposures at 300 kGy and 500 kGy, receiver performance degraded by only 1.5–1.6 dB. The next challenge is building a radiation-hardened transmitter, which may require exotic materials like diamond. ## Full article daily.dev links to this article rather than hosting it.
