Rocker oscillator time bases

Simon Nessim Henein, Ilan Vardi

Since the invention of the pendulum clock by Christiaan Huygens in 1657, precision timekeepers have been regulated by oscillators. Although the pendulum is not an isochronous oscillator, its introduction as a time basis for clock regulation led to a signif ...

Design of atomic clock cavity based on a loop-gap geometry and modified boundary conditions

Anja Skrivervik, Anton Evgeniev Ivanov

In this study, we investigate a concept that can be used to improve the magnetic field homogeneity in a microwave cavity applied in a novel, high-performance atomic frequency standard. We show that by modifying the boundary conditions in the case of a loop ...

Modeling and Design Techniques for 3-D ICs under Process, Voltage, and Temperature Variations

Hu Xu

Three-dimensional (3-D) integration is a promising solution to further enhance the density and performance of modern integrated circuits (ICs). In 3-D ICs, multiple dies (tiers or planes) are vertically stacked. These dies can be designed and fabricated se ...

Skew Variability in 3-D ICs with Multiple Clock Domains

Giovanni De Micheli, Hu Xu, Vasileios Pavlidis

The effect of process variations on the clock skew in three dimensional (3-D) circuits with multiple clock domains is investigated. In 3-D ICs, the combined effect of inter-die and intra-die process variations should be considered in the design of clock di ...
