Title:Machine Diagnostics System on a Chip
Abstract:The diagnostic systems in use in military machines are large and expensive. Other military machines could benefit from diagnostic and prognostic systems, but cannot afford the added size, weight and expense. Orbital Research proposes to address this issue by adapting the rugged ASICs that it has presently in development, and those planned for future development, into a single System on a Chip (SoC) using 3D IC stacking capability that is presently under development with Air Force SBIR funding. The SoC would incorporate all the required diagnostic and prognostic capability required by a variety of military applications. The SoC would reduce system size and cost while improving performance and reliability. With Silicon-on-Insulator process, each chip is isolated from the substrate by an insulating oxide layer of oxide forming superior isolating properties over semiconductor junction isolation (JI) or other forms of dielectric isolation (DI). By fabricating the ASICs using SOI technology, the operational temperature limit is increased to over 200įC, a key parameter in providing the ruggedness required for many of the machine diagnostic applications.

Title:Machine Diagnostics System on a Chip
Abstract:Under this SBIR program, Ridgetop Group will introduce the first single-chip, low-cost, low- power, and lightweight data monitoring solution for applications on rotating machinery. To develop this innovative miniature data collection platform, Ridgetop proposes to:  Provide a novel data collector using submicron integrated MEMS/CMOS fabrication processes  Define a commercialization strategy that will achieve volume pricing target of ≤$2.50 per unit, within five years  Provide a support interface for selected asset management platforms used by military and commercial customers. Ridgetop has a proven track record of delivering high-tech solutions like this one, tailored to customersí demanding end-applications. For example, we have recently designed a Data Memory Module (DMM) for commercial aircraft (Airbus A350) that has been qualified by the FAA to very rigorous DO-178B level C standards. We have also developed high- performance ASICs for other critical applications, including read-out electronics for satellite-borne camera systems, and prognostic sensors that detect wear-out in deep submicron technologies. Ridgetop has a complete Electronic Design Automation (EDA) tool-flow that enables us to function as a fabless semiconductor design house. We have successfully produced more than one dozen silicon designs over the last three years using these tools. Moreover, with our recent accreditation as a Trusted Supplier sponsored by the Defense Microelectronics Activity (DMEA), Ridgetop is now able to provide trusted design services for our DoD customers. Our facility and personnel are currently approved at SECRET level.

Title:Broadband Quadrature Mixers with Integrated I/Q Mismatch Calibration
Abstract:Communication SoC technology has advanced significantly over the past ten years resulting in highly integrated radio SoC chips for standards such as wireless Wi-Fi[xx], global position system (GPS), Bluetooth (BT), 3G cellular, digital TV (DTV), and cable modems. While most radio SoCís are narrowband (e.g. WiFi, GPS, BT, and cellular), future trends favor broadband software defined radios (SDR) and cognitive radios (CR). Both of these advanced radio concepts as well as some existing systems, such as DTV and cable tuners, require broadband quadrature mixers for up/down conversion with high linearity, low noise, high isolation, and superb I/Q matching. I/Q imbalance is especially detrimental to radio SoCís that must support high order modulation and tight channel spacing, typical in current and emerging radio systems. The proposed project will develop and demonstrate the feasibility of a broadband quadrature mixer that can achieve 54dB of image rejection ratio over a 3GHz bandwidth using robust integrated on-chip I/Q calibration in SOS process.

Title:Broadband Quadrature Mixers and I/Q Mismatch Reduction
Abstract:Silicon on Sapphire technology offer several advantages over bulk CMOS and BiCMOS technologies for the design of RFICs (RF Integrated Circuits) for the System on Chip radio applications. These advantages include superior radiation hardness, improved isolation between circuits, higher efficiency amplifiers, and more bandwidth per cost. In the last few years, RFIC designers have favored are Zero-IF and Low-IF architectures for these transceivers, due to the following main advantages over heterodyne architectures: 1. Eliminates the need to filter image of the receive band for Zero-IF architectures 2. Eliminates the IF section and its components 3. In many cases eliminates the off chip filtering after the LNA These new architectures all use quadrature mixing for which the key blocks are IQ modulators and demodulator which present an additional design challenges in terms of maintaining a low error-vector magnitude (EVM). One of the primary sources of impairments of EVM in the IQ modulators & demodulators is the gain and phase I/Q imbalance. Tahoe RF proposes a unique architecture for mitigating the impairments due to the gain and phase imbalances in the IQ modulators & demodulators and provides a new calibration method without the use of digital DSP, while maintaining low power consumption.
