Abstract
Methods and systems for on-chip impedance control to impedance match a configurable front end are disclosed and may include selectively enabling one or more amplifiers coupled to taps on a multi-tap transformer in a chip including the amplifiers. The impedances of the amplifiers may be matched to impedances of the taps on the transformer. The amplifiers may include low noise amplifiers wherein the input impedance of each of the low noise amplifiers may be different. The amplifiers may include power amplifiers wherein an output impedance of each of the power amplifiers may be different. The transformer may be coupled to an on-chip antenna, or to an antenna integrated on a package coupled to the chip. The multi-tap transformer may be integrated on the package. RF signals may be communicated via the selectively enabled amplifiers and the multi-tap transformer. The multi-tap transformer may include ferromagnetic materials integrated in the chip.
