In this tutorial paper we review the nature and requirements of optical fiber communications systems, and identify some trends in fiber systems that will have a bearing on the integrated circuits used to realize them. We concentrate on the optical interface layer, and only discuss up- and down-stream signal processing as it impacts the components of(More)
An increase of demand for high-speed communications leads to increasing the requirements for the interface between the digital and analog domains. That is why now design of high-performance analog-to-digital (ADC) and digital-to-analog (DAC) converters becomes so important. A lot of publications are dedicated to enhancement of ADC and DAC performance. For a(More)
The purpose of this paper is to describe and compare GaAs-InGaP HBT high sample rate track and hold amplifier designs. These are building blocks targeted to be used in next generation data conversion circuits. The track and hold designs are optimized to operate at 600 MSPS with 10 bits effective resolution. The two designs were fabricated to accommodate 0.5(More)
