Thin Pb(ZrTi)O/sub 3/ film capacitor devices were fabricated using RF sputtering techniques. The multiple-layer configuration of Si/SiO/sub 2//Ti/Pt was used as the substrate and bottom electrode. The top electrode was Pt. At 1 kHz, the dissipation factor (tangent loss) of PZT film capacitors processed at 100/spl deg/C was 8.35%. However the dissipation factor of PZT film capacitor processed at 60/spl deg/C was only 0.35%. The dielectric constant was calculated to be 32 at 1 kHz. After annealing at 400/spl deg/C, the dielectric constant increased about 33% to 43. The dielectric constant increased to 165 after annealing at 500/spl deg/C and to 1143 after annealing at 600/spl deg/C. The PZT film capacitors produced to-date had little dependence on frequency from 20 Hz to 100 kHz. The frequency dependence increased with increasing annealing temperature from 400/spl deg/C to 600/spl deg/C. Lowering the processing temperature from 100/spl deg/C to 60/spl deg/C resulted in a tremendous decrease in the dissipation factor from 8.3% to 0.35%.","PeriodicalId":171131,"journal":{"name":"Proceedings of the IEEE 2000 National Aerospace and Electronics Conference.

A control codec is an application of a heterogeneous codec, which replaces a traditional discrete analog control loop. This analog control loop includes an A/D (coder) plus a D/A (decoder), as well as other peripheral signal processing algorithms. Our application of the control codec is to improve the control of RF transponders in satellites. The codec is shown to have the ability to be optimized for a specific application as well as to be re-targeted to different fabrication lines. Because of the environmental demands on spaceborne devices several stable radiation-hardened SOI BiCMOS processes were used. The MIT Lincoln Labs AST Fully Depleted SOI deep-submicron process was also used as an example of re-targeting. Further, we develop the design for a control codec as an application of a general class of heterogeneous, process-independent codecs. The concepts for both a heterogeneous codec and a control codec are important additions to mixed-signal system design because they facilitate analog and mixed-signal block reuse. Our methodology implements a deliberate mixed-signal design decomposition, which enhances the reuse. This reuse is a major advancement in the development of evolvable hardware that uses both analog and digital signal processing in SoC applications.","PeriodicalId":171131,"journal":{"name":"Proceedings of the IEEE 2000 National Aerospace and Electronics Conference.

An end-to-end calibration means a full calibration of instrumentation from the physical input to the transducer to the output where the analog or digital signal is normally analyzed. It is difficult to stimulate mounted and embedded transducers with known physical inputs. Normally two people calibrate-one at the transducer holds or attaches the exciter and one operates the recorder. This new technique uses remote control structural exciters to stimulate measurement transducers contained in structures, with a measurable input level, and the output signal is communicated to a data recorder. The Air Force demonstrated this patented technique by using accelerometers in the laboratory. A commercial off-the-shelf vibration paging system sends a signal from a master control unit to individual exciters that stimulate accelerometers mounted on structures. A reference accelerometer measures the input. Engineers validated the technique using eight different exciters in a completely randomized block design experiment consisting of three 2-level factors: material, structural thickness and excitation mode. The engineers measured amplitude, frequency and transfer function between the accelerometers. This paper describes the invention and looks at potential field applications to insure data integrity in structural data acquisition systems on aging commercial and military vehicles.","PeriodicalId":171131,"journal":{"name":"Proceedings of the IEEE 2000 National Aerospace and Electronics Conference.
