Abstract
An integrated resistor-capacitor (RC) structure () is disclosed. The integrated RC structure includes a vertical capacitor () and a resistive element () disposed above the capacitor. The integrated RC structure uses a low ohmic substrate () to ensure a good ground return path for the capacitor. Further, a resistivity of the substrate is configured such that a top plate () of the capacitor provides a reference ground above a predefined frequency. The impedance of the resistive element () is matched, relative to the reference ground, to a predetermined resistance. As such, the resistance of the resistive element () can be controlled to provide an impedance controlled RC structure over a range of operating frequencies.
