ABSTRACT:
Methods and systems for dynamically tuning and calibrating an antenna using on-chip digitally controlled array of capacitors are disclosed. Aspects of one method may include dynamically tuning a mobile terminal antenna (MTA) using on-chip arrays of capacitive devices. The tuning may be, for example, to compensate for center frequency drift during operation of the mobile terminal. The tuning may be accomplished by selecting capacitive devices in the on-chip arrays of capacitive devices to use in conjunction with an inductive circuit coupled to the MTA, where the inductive circuit may be either off the chip or on the chip. Accordingly, an impedance of the circuit formed by the capacitive devices in the on-chip arrays of capacitive devices and the inductive circuit may be adjusted with respect to the MTA. A valid circuit configuration may include a configuration where no capacitive device may be selected for use with the inductive circuit.
