As per our calculations Input power to my FOG electronics is 40uW to 65uW (5mW is the laser diode power, 200m PM fiber spool, 1Mhz PZT freq)
" A novel technique for spectral processing of a fiber optic gyroscope" for as per this document do I need to capture signal frequency up to 4-5MHz, as per my resolution i need a 19bit ADC. To this specifications I could not find a ADC.
