Abstract
An analog-to-digital converter and a thermopile array. The analog-to-digital converter comprises: a reference voltage generation circuit comprising a voltage generation unit; a chopping modulation unit used to perform chopping modulation on a voltage signal generated by the voltage generation unit, and to modulate low frequency noise of the voltage signal into high frequency noise; and a low-pass filter used to eliminate the high frequency noise to obtain a reference voltage. The invention employs a simple structure to obtain a low noise reference voltage at low costs.
