Implementation of ternary identity cells using c.m.o.s. integrated circuits
This short article was my first publication with the IEE. The research project led to this discovery was about three weeks long. Why did nobody think of this identity cell before? Most ternary logic papers were modelling devices based on the concept of CMOS transmission gates, not by switches made of pure transistors. I did all of this work in my spare time while I was a Ph.D. student at Imperial College of Science and Technology. (My Ph.D. subject is a lot more complicated that this.)
Well, I did it first and the performance was great! Thanks to the availability of the CD4007 chip. Without it, I would not easily complete the investigation without contacting the IC fabrication companies. The total materials used in the project cost less than three pound sterling.
