This paper presents a new approach for extracting a scalable DC HEMT model. Scaling rules with unknown coefficients are assumed for each size dependent parameter, and the model parameter of different devices is thus correlated. A scalable model can then be extracted by multi-device optimization. The optimization is carried out on five devices with different gate width. In this way, accurate scaling...
Temperature dependent model is conventionally developed with 1) individual linear model extraction at each temperature and 2) temperature dependence extraction for each model parameter. A novel approach based on a multi-temperature optimization is proposed in this study. The new approach is faster and more accurate since the linear models at different temperatures are extracted simultaneously and...
This paper describes the challenges in Inertial Micro-Electro Mechanical System (MEMS) testing as compared to standard Application Specific Integrated Circuit (ASIC) testing. The most significant challenge in MEMS testing is having moving silicon parts surrounded by integrated circuitry (IC). Testing integrated circuits, whether analog or digital has its own complexity. However MEMS testing need to...
Stacked Crystal Filters (SCFs) are used in Bandpass filters and other applications where frequency control is required. SCFs use the Solidly Mounted Resonator (SMR) structure to enable operations at RF frequencies, typically 1-5 GHz. In the response spectrum of the SCFs, besides the main resonance mode, there are some unwanted additional modes present which affect the filter's performance away from...
In this paper, the results of a stacked crystal filter (SCF) are presented. It is shown that the bandwidth of the SCF can be designed by choice of electrode materials, device dimensions and use of external components such as inductors. This paper also discusses the fabrication of SCF along with the device layouts. A single stage and a two-stage SCF are designed and it is shown that the bandwidth of...
Using an experimental method, this study found that when a commercial was viewed immediately following a high-violence dramatic programming segment, children’s ad copy recognition scores were significantly lower and attitudes toward the ad and the advertised brand were significantly less favorable than when the commercial was viewed following a low-violence (but otherwise near-identical) program segment...
