PROTON characterization for a Dual 12bits 1.5Gsps Analog to Digital Converter dedicated up to S-Band domain (4.3GHz Bandwidth)

The Dual 12bits 1.5Gsps ADC is a dual channel single core S-band capable ADC intended for space applications, built using a true single core architecture providing high spectral purity. This device, designed with Teledyne E2V hardening expertise, and using the BiCMOS9 technology platform (featuring SiGeC NPN bipolar technology ft/fmax=166/175GHz and 0.13µm CMOS) from STMicroelectronics, has successfully passed the proton test, demonstrating its suitability in spaceborn digital receivers capable of sampling directly in the S-Band (2 - 4 GHz). With this test, we have validated the performances of our device, as that the proton contribution to the SEU error rate, estimated by the use of the PROFIT method with the heavy ions results, is very close to the results of the proton test.
