Octal to binary conversion using multi-input floating gate complementary metal oxide semiconductors

Multiple-input floating gate MIFG-MOSFETs and Floating Gate Potential Diagrams FPD used for conversion of quaternary-valued input and octal-valued input into corresponding binary-valued output in CMOS integrated circuit design environment. The method is demonstrated through the design of a circuit for conversion of quaternary quats into the corresponding binary bits (binary 00-11) and for conversion of octal octets into the corresponding binary bits (binary 000-111) in a standard 1.5μm digital CMOS technology. The novelty of this method is the simplicity of conversion where the output of the convertor can be directly connected to the binary CMOS circuits without the need of any interface due the compatibility of this convertor with the present CMOS process.
