Abstract
Systems for providing isolation of a bias signal relative to a radio frequency (RF) signal in an integrated circuit, and related circuits, modules, and methods, are disclosed herein. In one example embodiment, a system includes an inductor, a bypass capacitor, and a transmission line segment, which includes first and second ends and extends between the first and second ends. The first end is at least indirectly coupled to the bypass capacitor, the second end is at least indirectly coupled to a first additional end of the inductor, and a second additional end of the inductor is configured to be coupled at least indirectly to a device through which the RF signal is being communicated. The transmission line segment is configured to impart a non-negligible phase shift to a signal communicated between the first and second ends, or is configured to have a non-negligible effective inductance.
