Abstract

Aspects of a method and system for reconfigurable devices for multi-frequency coexistence are provided. In this regard, an IC may be configured based on a frequency of signals processed by the IC. In instances that the IC may process signals of a first frequency, the IC may be configured such that a loop communicatively coupled to the integrated circuit may function as an inductor. In instances that the IC may process signals of a second frequency, the IC may be configured such that the loop may function as an antenna for transmitting and/or receiving the signals. The loop may be within and/or on the IC and/or a package such as a multilayer package to which the IC may be bonded. The loop may be fabricated with stripline and/or microstrip transmission line. In instances that the loop may function as an inductor, the loop may be communicatively coupled as part of a VCO tank circuit.
