Design of Parallel Analog to Digital Converters for Ternary CMOS Digital Systems

Principles and possibilities for design and implementation of parallel analog to digital converters for application in ternary CMOS digital systems are considered and proposed in the paper. Such converters perform signal conversion from analog to ternary digital signal in CMOS ternary digital systems. First, general principle and structure for implementation and design of CMOS parallel analog to ternary digital converters are considered and proposed. Then, as an example and illustration of the design, concrete circuits for implementation of two digit parallel CMOS analog to ternary converters are proposed and described. Two types of such converters are considered and described: powerful type converters and simple type converters. All given solutions were analyzed using computer simulations. Descriptions and considerations were confirmed by the simulations.
