Abstract
A resistor divider network is disclosed having two or more thin or thick film resistive elements deposited on a substrate. Each of the resistive elements is divided into a number of resistive subelements which are interleaved so as to improve the temperature coefficient of ratio (TCR tracking) and improve the thermal coupling which greatly improves the ratio constancy over a wide range of input voltage. There are an odd total number of resistive subelements, the subelements of each main element having equal resistances.
