Abstract
A voltage integrator circuit and a filter circuit are configurable to adjust their outputs in order to compensate for various circuit elements' variations with temperature. The voltage integrator circuit performs temperature compensation through the adjustment in resistance value of a single resistive element in response to a received control signal. The control signal correlates with a detected temperature value and causes the resistive element to adjust its resistance value in a manner that maintains the transfer function of the voltage integrator circuit under varying temperatures. The filter circuit comprises one or more of the voltage integrator circuits and maintains its transfer function under varying temperatures.
