Virtual Capacitor Concept for Computationally Efficient and Flexible Real-Time MMC Model

Drazen Dujic, Stefan Milovanovic, Min Luo

This paper demonstrates the splitting of the modular multilevel converter real-time simulation model into several independent parts through the use of the virtual capacitor concept. As a result, the number of state-space matrices the real-time solver needs ...

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 ...

Low-power clock distribution networks for 3-D ICs

Giovanni De Micheli, Vasileios Pavlidis, Somayyeh Rahimian Omam

Designing a low power clock network in synchronous circuits is an important task. This requirement is stricter for 3-D circuits due to the increased power densities. Resonant clock networks are considered efficient low-power alternatives to conventional cl ...

The Combined Effect of Process Variations and Power Supply Noise on Clock Skew and Jitter

Giovanni De Micheli, Vasileios Pavlidis, Hu Xu, Wayne Burleson

In modern VLSI circuits, a large number of clock buffers are inserted in clock distribution networks, which are significantly affected by process and power supply noise variations. The combined effect of process variations and power supply noise on clock s ...

Dispensing and Hermetic Sealing Rb in a Miniature Reference Cell for Integrated Atomic Clocks

Herbert Shea, Peter Ryser, Thomas Maeder, Fabrizio Vecchio, Vinu Lalgudi Venkatraman

An innovative method for filling and sealing the reference cell for a Rubidium (Rb) integrated atomic clock is presented. We used a simple, low-temperature solder sealing technique for producing mini-cells of the size of 12 x 10 x 2 mm, suitable for Rb min ...
