I intend to design a device to measure the power factor without the
use of a microcontroller. In the design, the measured angle will be
given by a simple DC voltage, e.g. 30° = pi/6 rad = 0.523 V
A problem that occurs is calculating the cosine of this voltage. In a
discrete setup, I will use Taylor series and realise it with analog
multipliers and a few operational amplifiers.
Before starting this, I would like to know if a single IC exists that
can make this calculation at once, eg 0.523 V IN results in cos(0.523)
= 0.866 V OUT
Thanks for help
