Performance Characteristics of a 4-Bit 828-Megasamples/Sec Electro-Optic Analog-to-Digital Converter.

摘要

An electrooptic A/D converter which utilizes optical sampling and which is capable of converting analog signals with bandwidths up to 414 MHz is under development. A device has been fabricated and individual bit channels tested using a beat-frequency technique. The operational principles, converter structure and testing results are summarized.
