Technical Abstract (Limit 2000 characters, approximately 200 words)

NASA Science Mission Directorate’s (SMD) programs demand an innovative single-chip 6-bit 20GSPS analog to digital converter (ADC) capable of surviving and maintaining performance in extreme environments for use in next generation low-power, rad-tolerant broad band spectrometer back ends for microwave radiometers. Broadband spectrometers in Earth observing, planetary, and astrophysics missions have a critical need for greater sensitivity detector arrays for imaging, spectroscopy, and polarimetric capabilities, which can be demonstrated on ground, airborne, balloon, suborbital rocket instruments, or uninhabited aerial vehicle (UAV) platforms. Future cloud, water and precipitation missions like Soil Moisture Active Passive (SMAP) require higher frequency electronics, with small form factors and high power added efficiencies (PAE). 

Alphacore proposes a competitively disruptive ADC, based on its similar solutions, to meet NASA’s request for development of advance science instruments, observatories & sensor systems. The rad hard ADC, with Size Weight and Power (SWaP) efficiencies, will start with existing Alphacore validated silicon to exceed a sampling rate of 20GSPS with an effective number of bits >6 and a straightforward FPGA interface. The ADC consists of a high-performance, low-power design that can be developed as a stand-alone chip or licensed as an IP block for use in advanced system-on-chip (SOC) architectures. The ADC employs a silicon proven radiation hardened flash architecture using a common FD-SOI wafer process node
