Intra-data center links are subject to transmission impairments that pose challenges for
efficient scaling of per-wavelength data rates beyond 100 Gb/s. Limited electrical and optical …

Today's ultra-wideband optical equipment enables fiber-based data links with up to 1.6
Tbit/s per wavelength at a symbol rate of 128 Gbaud. However, high input signal path losses …

We report on a 2: 1 analog multiplexer (AMUX) circuit in 130-nm SiGe BiCMOS technology.
The technology offers HBTs with peak f T of 470 GHz and f max of 650 GHz. S-parameter …

We demonstrate a technology to extend the bandwidth of optical transmitters based on
optical time interleaving. An optical time-interleaving in-phase-and-quadrature (IQ) …

A novel background calibration technique for Time-Interleaved Analog-to-Digital Converters
(TI-ADCs) is presented in this paper. This technique is applicable to equalized digital …

Spectrally efficient modulation formats become essential for optical network scaling as the
demand for routed data streams exceeds the present wavelength-division multiplexing …

This paper connects the linear steady-state systematic error models of the time-and
frequency-interleaved analog-to-digital converters (ADCs). Exposing their relations is of …
