Energy-Efficient Design Techniques for High-Speed Wireline Serial Links

Firat Çelik

The exponential growth in computing power and multimedia services has caused a tremendous increase in data traffic in recent years. This increase in data traffic brings a strong demand for data bandwidth of electrical input/output (I/O) links and pushes th ...

Multi-Tone Signaling and ADC-Based Digital Receiver for High-Speed Wireline Serial Links

Gain Kim

The exponential growth of Internet traffic and related demands for higher communication speed pushes processor-to-processor and processor-to-memory interconnects to provide further higher data-rate. Often time, processor-to-memory interconnectsâ speed is ...

Digital Silicon Photonic MEMS Phase-Shifter

Niels Quack

We report on a 4-bit digital silicon photonic MEMS phase-shifter with sub-microsecond switching time and low power consumption (< 10 uW). The device consists of 4 digitally switched phase-shifting units, which in total enable phase shift from pi/8 to 15pi/ ...

High sensitivity field asymmetric ion mobility spectrometer

Jürgen Brugger, Giovanni Boero, Philippe Marmillod, Alessandro Valentino Matheoud, Mario Andres Chavarria Varon

A high sensitivity field asymmetric ion mobility spectrometer (FAIMS) was designed, fabricated, and tested. The main components of the system are a 10.6 eV UV photoionization source, an ion filter driven by a high voltage/high frequency n-MOS inverter circ ...

Phase analysis of amplitude binary mask structures

Hans Peter Herzig, Toralf Scharf, Krishnaparvathy Puthankovilakam

Shaping of light behind masks using different techniques is the milestone of the printing industry. The aerial image distribution or the intensity distribution at the printing distances defines the resolution of the structure after printing. Contrast and p ...

Analytic derivation of the (k/j)-order modulation envelopes in the sum of two mistuned (co)sine waves

Isaac Amidror

The beating effects which may occur in the sum of two mistuned cosine (or sine) functions whose frequencies f1, f2 satisfy f2 ≈ (k/j)f1 (where k/j is a reduced integer ratio) are known as “beats of mistuned consonances”. They have already been investigated ...

Efficient, compact and low loss thermo-optic phase shifter in silicon

Christophe Marcel Georges Galland

We design a resistive heater optimized for efficient and low-loss optical phase modulation in a silicon-on-insulator (SOI) waveguide and characterize the fabricated devices. Modulation is achieved by flowing current perpendicular to a new ridge waveguide g ...
