We present a novel RF identification transponder based on nonlinear transmission lines (NLTLs). The NLTLs provide an effective solution to self-jamming with the harmonic generation property, and they are passive, compact, and offer easy impedance. Three NLTLs are fabricated with a different Bragg cutoff frequency <i>fT</i> in an IBM 8RF 0.13-&#x03BC; m CMOS(More)
We propose and demonstrate accurate 3D real-time indoor localization via broadband nonlinear backscatter in passive devices. The proposed method does not need any relative motion between a reader and a tag or the use of reference anchor nodes. In the conventional radio frequency identification (RFID) system, a passive tag responds to a reader by switching(More)
To accurately simulate modern semiconductor process steps, TCAD tools must include a variety of physical models and numerical methods. Increasingly complex physical formulations are required to account for eeects that were not important in previous generation of technology. As a speciic example, the impurity diiusion mechanisms owing to point defects and(More)
We have used a human salivary gland cell line (HSG) as a possible in vitro model to evaluate the effects of IFN-gamma on human salivary gland epithelium (Wu et al., 1994, 1996, 1997). In the present study, we examined the JAK-STAT signal-transduction pathway in IFN-gamma-treated HSG cells. We demonstrate that JAK2 and Stat1 are phosphorylated at tyrosine(More)
The performance of six self-monitoring blood glucose (SMBG) machines (Accutrend, Reflolux S, Companion 2, Glucometer GX, Glucometer IV and One Touch II) were examined using venous blood samples from 88 patients. Whole blood glucose (BG) values were measured by four machines from each brand. Machine-generated whole blood glucose (BG) values were corrected(More)
Millimeter-precision meter-distance real-time indoor ranging capability is challenging due to multipath reflections in a rich scattering environment. Traditional continuous wave (CW) phase-based ranging methods, although simple and flexible, are vulnerable to phase offsets and interferences. We improve the previous CW approach by passive broadband harmonic(More)
Using an external electric field, one can modulate the band gap of Bernal stacked bilayer graphene by breaking the A-[Formula: see text] symmetry. We analyze strain effects on the bilayer graphene using the extended Hückel theory and find that reduced interlayer distance results in higher band gap modulation, as expected. Furthermore, above about 2.5 Å(More)
Electronic detection of the binding event between biotinylated bovine serum albumen (BSA) and streptavidin is demonstrated with the chemoreceptive neuron MOS (CnuMOS) device. Differing from the ion-sensitive field-effect transistors (ISFET), CnuMOS, with the potential of the extended floating gate determined by both the sensing and control gates in a(More)
We propose the nonlinear transmission line (NLTL) as an effective global interconnect method that offers capabilities of rise/fall edge sharpening, signal shaping/amplification, and impedance matching. Interconnect line characteristics of NLTLs implemented with the MIT Lincoln Lab 0.18/spl mu/m FDSOI (fully-depleted silicon-on-insulator) CMOS process are(More)
