Abstract

Analog-to-digital conversion requires input amplitudes in the volts range. On the other hand, optical or magnetic sensors deliver sinusoidal signals in the millivolts range and these signals need to be treated digitally. So, two main units will be needed: (1) a programmable gain amplifier and (2) a digital control circuit to maintain certain voltage at the output of the programmable gain amplifier.
