A 4.8pJ/b 6Gb/s ADC-Based PAM-4 Wireline Receiver Data -Path with Cyclic Prefix in 14nm FinFET

Andreas Peter Burg, Cosimo Aprile, Yusuf Leblebici, Alessandro Cevrero, Lukas Kull, Gain Kim, Ilter Ozkaya, Thomas Toifl

This work presents an ADC-bascd receiver (RX) data-path for frame-based PAM-4 modulation with a cyclic prefix (CP). Similar to discrete multi-tone (DMT) modulation, a frame of PAM-4 symbols arc protected from the channel delay spread by the CP taps. A PAM- ...

ISI Sensitivity of PAM Signaling for Very High-Speed Short-Reach Copper Links

Seyed Armin Tajalli, Yusuf Leblebici, Firat Çelik, Ayça Akkaya

This paper presents a comparative study, analyzing the potentials of pulse amplitude modulation (PAM) for implementing next generation high-speed copper wireline links. This comparative study analyzes the sensitivities of PAM2, PAM4 and PAM8 to inter-symbo ...

Design Considerations and Performance Trade-Offs for 56Gb/s Discrete Multi-Tone Electrical Link

Yusuf Leblebici, Gain Kim, Thomas Toifl

For communicating over mid-to-long-reach electrical links at a data-rate above 56Gb/s, ADC-based receiver (RX) has become a dominant architecture due to its strong equalization capability using complex digital signal processing algorithm benefiting from th ...

Improved off‐resonance phase behavior using a phase‐inverted adiabatic half‐passage pulse for 13 C MRS in humans at 7 T

Rolf Gruetter, Lijing Xin, Daniel Gallichan, Eulalia Serés Roig

In vivo (13) C MRS at high field benefits from an improved SNR and spectral resolution especially when using surface coils in combination with adiabatic pulses, such as the adiabatic half-passage (AHP) pulse for (13) C excitation. However, the excitation p ...
