To enhance sampling rates of CMOS digital-to-analog converters (DACs), analog
multiplexing of several DAC output signals in the time domain provides a solution. In this …

Future generations of optical networks will require optical interfaces that operate beyond 1
Tb/s to keep up with the exploding worldwide Internet data capacity. The data converters …

With the increasing demands in modern communications, the concepts of energy-efficient
and low-cost processors have received a lot of attention from researchers in recent years …

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) …

In recent years, cryogenic minimum quantity lubrication (CMQL) has increasingly become
the focus of research. With this cooling strategy, it is possible to cool and lubricate the cutting …

We present a 2: 1 analog multiplexer evaluation board for increasing the analog bandwidth
of digital-to-analog converters, based on an integrated circuit in IHP's new 130 nm SiGe …

Future high-speed optical communication requires continuous increases in both information
rate (IR) and symbol rate. An analog multiplexer (AMUX) interleaves individually generated …

Generation of real-valued digital-subcarrier-multiplexed PCS-256QAM is demonstrated
using a 120 GSa/s BiCMOS analog multiplexer. A record per-modulation-dimension spectral …

A 2: 1 analog multiplexer (AMUX) module based on a SiGe-HBT IC is presented. The AMUX
module offers a 6-dB analog signal path bandwidth of 61 GHz. We show a 120 GBd 4-level …

Extreme high-speed and high-capacity communications are one of the requirements for
technologies to be implemented in the new generations of wireless networks. Moreover …
