Picosecond imaging circuit analysis
نویسندگان
چکیده
A newly developed optical method for noninvasively measuring the switching activity of operating CMOS integrated circuit chips is described. The method, denoted as picosecond imaging circuit analysis (PICA) can be used to characterize the gate-level performance of such chips and identify the locations and nature of their operational faults. The principles underlying PICA and examples of its use are discussed.

A picosecond Josephson junction model for circuit simulation
The first order series expansion of the time dependent Josephson equation allows a precise simulation of the switching dynamic of picosecond Josephson junctions. The junction model is quite as efficient as the RSJC model in computer calculations. Numerical examples illustrate its domain of application for picosecond junctions in a circuit environment by comparison with the RSJC model. Revue Phy...
متن کاملPicosecond spectral coherent anti-Stokes Raman scattering imaging with principal component analysis of meibomian glands.
The lipid distribution in the mouse meibomian gland was examined with picosecond spectral anti-Stokes Raman scattering (CARS) imaging. Spectral CARS data sets were generated by imaging specific localized regions of the gland within tissue sections at consecutive Raman shifts in the CH(2) stretching vibrational range. Spectral differences between the location specific CARS spectra obtained in th...

متن کاملA Novel Picosecond Pulse Generation Circuit Based on SRD and NLTL
Because of the importance of ultra-wideband (UWB) radar in various applications, short pulse generation in UWB systems has attracted a lot of attention in recent years. In order to shorten the pulse, nonlinear transmission line (NLTL) is imported, which expands the application of step recovery diode (SRD) for pulse generation. Detailed analysis and equations for this SRD and NLTL-based pulse ge...
متن کاملMulticolor stimulated Raman scattering microscopy with a rapidly tunable optical parametric oscillator.
Stimulated Raman scattering (SRS) microscopy allows label-free chemical imaging based on vibrational spectroscopy. Narrowband excitation with picosecond lasers creates the highest signal levels and enables imaging speeds up to video-rate, but it sacrifices chemical specificity in samples with overlapping bands compared to broadband (multiplex) excitation. We develop a rapidly tunable picosecond...
