Laser frequency noise (LFN) is the dominant source of expected in Interferometer Space Antenna (LISA) mission, at $\sim$7 orders magnitude greater than typical signal from gravitational waves (GWs). Time-delay interferometry (TDI) suppresses LFN to an acceptable level by linearly combining measurements individual spacecraft delayed durations that correspond their relative separations.

Calculation of High-Speed VLSI Interconnects S. Abbaspour, A.H. Ajami, M. Pedram, and E. Tuncer Dept. of EE Systems, University of Southern California, Los Angeles, CA 90089 Magma Design Automation, Santa Clara, CA 95054 Abstract This paper describes an efficient threshold-based filtering algorithm (TFA) for calculating the interconnect delay and slew (transition time) in high-speed VLSI circui...

Electronically controlled phased-array antennas can adaptively scan radiated beams in three-dimensional space without mechanically moving parts. While most of the research on phased-array antennas has been focusing on broadband beam steering less attention has been devoted to null steering. Broadband null steering requires a beamformer that can generate variable and frequency independent true t...

The problem of ordering and sizing parallel wires residing in a single metal layer within an interconnect channel is addressed in this paper. Wires are ordered such that cross-capacitances between neighboring wires are optimally shared for circuit delay minimization. Using an Elmore delay model including cross capacitances, an optimal wire ordering is uniquely determined, such that average sign...
