Abstract We firstly report a 2-μm all-fiber nonlinear pulse compressor based on two pieces of normal dispersion fiber (NDF), which enables high-power scaling ability watt-level and high compression ratio 13.7. With the NDF-based compressor, 450-fs laser pulses with repetition rate 101.4 MHz are compressed to 35.1 fs, corresponding 5.2 optical oscillation cycle at wavelength region. The output a...

This paper presents the fabrication, modeling, characterization and analysis of silicon-embedded, aircore, three-dimensional toroidal inductors for power converter applications. The inductors are fabricated within deep silicon recesses by means of a 3-D silicon shadow mask coupled with electroplating techniques. The losses in the inductor and the surrounding silicon are analytically modeled usi...

A tuning scheme for continuous-time highbiquad filters is presented. An improvement over the existing implementation of the modified-LMS -tuning scheme is proposed and efficiently combined with the frequency tuning based on phase-locked loops. The proposed scheme takes much less area without compromising the accuracy achieved previously. The proposed unified and 0-tuning scheme does not require...

We present a correlation between the ACME/SP94 CMB anisotropy data at 25 to 45 GHz with the IRAS/DIRBE data and the Haslam 408 MHz data. We find a marginal correlation between the dust and the Q-band CMB data but none between the CMB data and the Haslam map. While the amplitude of the correlation with the dust is larger than that expected from naive models of dust emission it does not dominate ...

©2011 IEEE Plotting the individual components is shown in Fig. 11. Adding the pulses gives the solution for V 10, t 2 shown in Fig. 12. All of the results of the above examples were validated using the PSPICE circuit analysis computer program. Use of the exact lossless transmission line model in PSPICE for more complicated lossless transmission-line problems is highly recommended [1]. VI. Refer...
