Abstract:
1. An integrated circuit comprising: an inductor comprising a coil portion and an empty area in the center of the coil portion, wherein the inductor is a degeneration inductor that is part of a low noise amplifier (LNA); additional circuitry, wherein the additional circuitry is located within the empty area in the center of the coil portion, wherein the additional circuitry is arranged such that an impact of the additional circuitry on an inductance and a quality factor of the inductor is minimized, and wherein the additional circuitry comprises a resistor capacitor (RC) clamp; and routing lines connected to the additional circuitry that extend across the coil portion and that are positioned to reduce inductive coupling between the additional circuitry and the inductor.
