Serial link receivers with ADC front-ends are emerging in order to scale data rates over high attenuation channels. Embedding partial equalization inside the front-end ADC can potentially result in lowering the complexity of back-end DSP and/or decreasing the ADC resolution requirement, which results in a more energy-efficient receiver. This paper presents a 6b 1.6GS/s ADC with a novel embedded DFE...
In this paper, planar microwave oscillators are used to measure the dielectric constant of organic liquids for the first time. Dielectric constant of an unknown material is calculated based on the change in oscillation frequency caused by the interaction of the material-under-test (MUT) with a split-ring resonator (SRR). The dielectric constants of small quantities of acetic acid, xylene, isobutanol...
Optical interconnect with its terahertz bandwidth, low loss, and low cross-talk has been proposed to replace electrical interconnect between chips [1]. This paper describes results for both near and long-term chip-to-chip optical interconnect architectures.
A low-voltage 90 nm CMOS optical interconnect transceiver operating at 1550 nm is presented. This is the first system demonstrated using the recent quasi-waveguide angled facet electroabsorption modulator (QWAFEM), featuring simple electronic and optical packaging.
Optics potentially addresses two key problems in electronic chips and systems: interconnects and timing. Short optical pulses (e.g., picoseconds or shorter) offer particularly precise timing. Results are shown for optical and electrical four-phase clocking, with <1 ps rms jitter for the optical case.
