Considering Multipliers, Part 1
[The Wit and Wisdom of Dr. Leif–7]

Multipliers exploiting translinear loops, current-mirrors, current conveyors, and linear gm cells continue to be indispensable more than sixty years since the very first fully monolithic ICs were fabricated in 1967. In this futuristic tale, Drs. Newton Leif and Niku Chen discuss multiplier topologies, uses, and history. Leif also provides some hints as to how neurons, which are translinear, behave exactly like bipolar junction transistors.

I enjoyed reading this rather rambling article. As a sometimes chemist I would like to point out the the negative ion is not Na-. The negative ion is Cl-.

Although I do mostly digital design, I have been around long enough to have used analog computers to solve problems. I think this article shows insight into future development. The speed power product for digital has about run its course.

Digital will always be around to manage numeric data and text. However, analog will be the solution for control systems that need to make intelligent decisions.
