Abstract:
Disclosed is a circuit for controlling the temperature and the bias voltage of a detector used by an X-ray analytical instrument. The circuit uses a single common reference voltage for the temperature measurement and for all the ADCs and DACs in the circuit, resulting in reduced drift and improved reproducibility of detector temperature and bias voltage. ADCs with a larger number of bits are used to produce precision values of the temperature, the bias voltage, and their respective setpoints. The setpoints are digitally varied until the precision setpoint values correspond to desired values of temperature and bias setpoints.

Claim (Index 14):
A circuitry for providing a bias voltage via a bias power supply to a detector of an X-ray analyzer, the circuitry comprises:\n a bias voltage measurement element producing a bias measurement voltage, a controlling circuit providing a control signal for controlling the bias power supply, the controlling circuit further comprises:\n a single common reference element providing a common reference voltage, \n a bias digital-to-analog converter (DAC) configured to produce a setpoint voltage based on a pre-determined bias setpoint value and the reference voltage, \n a bias analog-to-digital converter (ADC) configured to digitize the bias measurement voltage and the bias setpoint voltage and produce a precision bias setpoint value, wherein the precision bias setpoint value is used to produce an adjusted bias setpoint voltage, \n a comparator producing a differential value between the bias voltage and the adjusted bias setpoint voltage wherein the differential value is used as a basis for the control signal, wherein the common reference voltage is referenced by the bias DAC and the bias ADC.
