TECHNICAL ABSTRACT (Limit 2000 characters, approximately 200 words)
The proposed project aims to develop a 20GSps 6-bit radiation hardened analog to digital converter (ADC) required for microwave radiometers being developed for space and air borne earth sensing applications. Aiming to improve performance and to reduce the size of the electronics, high resolution, high-sampling rate, power efficiency and low spur energy are the requirements for ADCs employed for direct digitization in microwave radiometers. The proposed 20GS/s 6-bit interleaved successive approximation (SAR) ADC is intended to achieve >5 ENOB and 20GHz input bandwidth. A number of innovations will be introduced to the ADC in order to combine low power consumption with high signal to noise and distortion (SINAD), and spurious free dynamic range (SFDR) which is important for spectrography applications. A novel low glitch energy technique coupled with interleaved samples aperture calibration will be introduced to achieve digitization accuracy, improve linearity and achieve high sampling rate. The proposed ADC ASIC will contain on-chip all necessary components, including a frequency synthesizer, serial interface, standard interface with an FPGA, and design-for-testability features. The ADC will be implemented using a deep submicron CMOS technology. The project's Phase I will provide the proof of feasibility of implementing the proposed ADC. Phase II will include finishing design, fabrication, testing and delivering the ADC prototypes which will be ready for commercialization in Phase III.

POTENTIAL NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
The low power 20GS/s 6-bit ADC featuring power optimization capability has great potential in current and future NASA missions. Besides targeted application for microwave radiometers, the proposed ADC ASIC is directly applicable to systems seeking low-power, radiation hardened, flexible solution for direct digitization of wide bandwidth RF signals, such as deep space communication radios and/or reconfigurable radios for SDR applications. For example, this ADC can be employed in NASA missions using Ku band, such as OIB (airborne program for precise sea and ice elevation monitoring) or ISS based CONNECT (COmmunications, Navigation, and NEtworking reConfigurable Test-bed).

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
In addition to its primary application in spectral radiometry systems, the proposed wideband 20GS/s ADC and its building blocks will be targeting other commercial and military related markets which require high speed capture and digitization of wideband signals. Commercial applications include wireless (WiMAX, 3G, 4G) and fiber optic communication (40G and 100G Ethernet). The ramp-up of 100G Ethernet technologies raises the industry's demand for adequate test equipment. Therefore, the proposed ADC has great commercialization potential in this market segment. Possible military applications include high speed, secure communication and data transmission systems and millimeter-resolution radars.
