Abstract: An apparatus include one or more DACs and a resistor divider are configured to generate a variable bias voltage VBIAS with respect to a CM voltage VCM. The CM voltage VCM is applied to a cathode of one or more thermopiles or a negative input of one or more amplifiers to prevent saturation and over range of one or more low voltage readout amplifiers and one or more ADCs.
