Design and Measurement of an Inductance-Oscillator for Analyzing Inductance Impact on On-Chip Interconnect Delay
A newly devised inductance-oscillator (iOSC) has been developed which evaluates inductance impact on on-chip interconnect delay. iOSC is a ring oscillator which is comprised of a set of wires each with different loop inductance and accurate on-chip counter. The equivalent distance to the nearest ground grid, which serves as the current return path, is varied to control wire inductance. A test c...

متن کاملAbsolute measurement of surface roughness.
In an interferometer which uses a reference surface, the measured surface heights correspond to the difference between the test and reference surfaces. To accurately determine the rms roughness of supersmooth surfaces, the effects of the reference surface roughness need to be removed. One technique for doing this involves averaging a number of uncorrelated measurements of a mirror to generate a...
متن کاملMeasurement of absolute transition dipole moment functions
We describe a two-laser experiment using optical-optical double resonance fluorescence and Autler– Townes AT splittings to determine the NaK 3 1 →1 X 1 +, 2 A 1 + absolute transition dipole moment functions. Resolved 3 1 →A 1 + and 3 1 →X 1 + fluorescence was recorded with the frequencies of a titanium-sapphire laser L1 and a ring dye laser L2 fixed to excite particular 3 1 =19,J=11, f ←A 1 + ,...
متن کاملPrecision absolute positional measurement of laser beams.
We describe an instrument which, coupled with a suitable coordinate measuring machine, facilitates the absolute measurement within the machine frame of the propagation direction of a millimeter-scale laser beam to an accuracy of around ±4 μm in position and ±20 μrad in angle.
