Five Bit, Five Gigasample TED Analog-to-Digital Converter Development.
Abstract
The objective of this work is to develop a high speed (gigasampling rate per second range) multibit A/D converter based on the characteristics of GaAs transferred-electron logic devices (TELD) and the monolithic GaAs IC technology developed at TRW. The TELD is a threshold device which has been used in conjunction with a FET comparator circuit in a successive approximation or serial A/D converter. In orde to make consideration of the delay path in the matching between the A/D cells manageable, a low frequency direct coupling approach was adopted for a 5-bit three gigasample per second A/D converter. Following this approach, an optimized computer-aided design and a complete circuit layout has been accomplished. (Author)
