High Performance Rad Hard Analog to Digital Converter Architectures
Agency / Branch:
DOD / MDA
Electronic components for future space based radar systems on chip (SOC) must function correctly in natural and radiation filled environments while providing state-of-the-art performance. The corresponding SOC must employ advanced, extra low-power, radiation-hardened (RH), analog-to-digital converters (ADCs) capable of operating at multi-giga sampling speeds. To satisfy the described needs, we propose to develop an ADC block with 9 bits of resolution and up to 10Gs/s of sampling speed. The 9 bit wide data will be demultiplexed by a factor of eight to a rate of 1.25Gb/s for direct loading into a following FPGA where signal processing will be performed. Our patent-pending radiation-hardening techniques incorporate a methodology based on protection and redundancy, which provides both total ionization dose (TID) and single-event upset (SEU) tolerance within the IC. The proposed high performance characteristics of the ADC will be achieved by utilizing an advanced SiGe IC fabrication technology.
