High speed analog-to-digital conversion with silicon photonics
Sampling rates of high-performance electronic analog-to-digital converters (ADC) are fundamentally limited by the timing jitter of the electronic clock. This limit is overcome in photonic ADC’s by taking advantage of the ultra-low timing jitter of femtosecond lasers. We have developed designs and strategies for a photonic ADC that is capable of 40 GSa/s at a resolution of 8 bits. This system re...
متن کاملHigh-Speed Analog-to-Digital Converter Survey
Every year, higher and higher sampling rates as well as lower and lower power dissipations are reported in the literature. The table in Figure 1 lists published results for nineteen highspeed, low-resolution A/D converters (mostly six to eight bits), along with a few commercial parts, representing a wide variety of fabrication technologies. In the following sections, these reported specificatio...
متن کاملHigh - Speed Oversampling Analog - to - Digital Converters
This paper is mainly tutorial in nature and discusses architectures for oversampling converters with a particular emphasis on those which are well suited for high frequency input signal bandwidths. The first part of the paper looks at various architectures for discrete-time modulators and looks at their performance when attempting high speed operation. The second part of this paper presents som...
متن کاملIntegrated Optical Components in Silicon for High Speed Analog-to- Digital Conversion
Advances in femtosecond lasers and laser stabilization have led to the development of sources of ultrafast optical pulse trains that show jitter on the level of a few femtoseconds over tens of milliseconds and over seconds if referenced to atomic frequency standards. These low jitter sources can be used to perform opto-electronic analog to digital conversion that overcomes the bottleneck set by...
متن کاملAnalog to Digital Conversion
1 ADC TYPES Analog-to-Digital Converters (ADCs) transform an analog voltage to a binary number (a series of 1’s and 0’s), and then eventually to a digital number (base 10) for reading on a meter, monitor, or chart. The number of binary digits (bits) that represents the digital number determines the ADC resolution. However, the digital number is only an approximation of the true value of the ana...
