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.

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

Excel and Google Sheets have three functions to calculate the internal rate of return: IRR, XIRR, and MIRR. Learn how these functions can calculate investment returns.

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 ...
