Voltage divider circuit assembly and method

A circuit assembly comprising:

• plural resistors conductively coupled in a series with each other between input terminals that are configured to receive an input voltage across the input terminals, at least one of the resistors including an external resistor that is disposed between sensing terminals, wherein the sensing terminals are configured to conduct an output voltage that is the input voltage divided by the resistors in the series;
• an external electrostatic shield conductively coupled with the series of the resistors with the external resistor disposed outside of the external electrostatic shield and the resistor or the resistors in the series other than the external resistor disposed inside the external electrostatic shield;
• and
• one or more internal electrostatic shields conductively coupled with the series of resistors and disposed inside the external electrostatic shield, wherein a first internal resistor in the series of resistors is disposed inside the external electrostatic shield and outside of the one or more internal electrostatic shields, and wherein at least one remaining resistor of the series of resistors other than the external resistor and the first internal resistor is disposed inside the one or more internal electrostatic shields.
