Analog to digital signal converters for BiCMOS quaternary digital systems

Possibilities of practical development, design and implementation of analog signal to quaternary digital signal converters for application in BiCMOS quaternary digital circuits and systems are considered, proposed and described in the paper. General approaches and general structure for implementation and design of parallel analog to quaternary BiCMOS digital signal converters are proposed and described. Two digit parallel analog to quaternary BiCMOS digital signal converters are proposed and described as the illustration of proposed way for the converters design and implementation. More possibilities of converters development, design and implementation were considered and described. Two types of such converters are described in more details: the basic type converters and the modified type converters. Given solutions have been analyzed by computer simulations. All descriptions and considerations have been confirmed by computer simulations. Some of the computer simulation results are given in the paper.
