Techniques for generating reference voltages and reference currents from a supply voltage are disclosed. A disclosed reference voltage and reference current generator circuit includes a combination of transistor (e.g., MOS) devices and interconnect resistors. The interconnect resistors have temperature coefficients that are selected to negate temperature sensitive effects in the transistor devices due to electron mobility temperature behavior in the transistor devices. The interconnect resistors may be implemented as resistor stacks that include interconnected metal layers separated by electrically insulating layers.
