A new current mode variable-gain amplifier (VGA) is developed. The new circuit is based on a novel approximation function that is very close to the ideal exponential relation over a very wide range.

Functions are one of the most fundamental concepts in mathematics, serving as a cornerstone for topics in algebra, calculus and beyond. Basics of functions are stepping-stone to success in functions ...

Exponential growth is a pattern of data that shows greater increases with passing time, creating the curve of an exponential function.

The exponential function polynomials can be computed through the integrated DNA strand displacement circuits. Finally, through visual DSD software verification, this design can realise the computation ...
