Noise immunity characteristics of integral analog-to-digital converter including voltage-to-frequency converter for noise on power-supply-lines

In this study, the malfunction characteristics of the integral analog-to-digital converter including voltage-to-frequency converter for the incident conductive noise on power-supply-line is experimentally clarified. It is concluded that the noise immunity of the analog-digital converter for incident conductive noise on power-supply line is dominated by the response characteristics to noise immunity of control multi-vibrator installed in the voltage-to-frequency converter and the integrator shows the abnormal response according to control multi-vibrator's malfunction.
