Abstract: The present invention provides a method and an apparatus for controlling a Q-factor for a filter. The method comprises stabilizing an active feedback (300) to provide a variable feedback in a filter (120a), varying the active feedback based on an input signal (310a) to the filter, and producing a desired Q-factor for the filter at a first frequency band, in response to the variable feedback. The method further comprises reconfiguring a center frequency and a bandwidth of the filter based on a channel bandwidth of the input signal to the filter to adjust the Q-factor for the filter in response to a second frequency band different than the first frequency band. By reconfiguring a center frequency and a bandwidth of a filter, the Q-factor for the filter, such as a flexible or reconfigurable filter, may be controlled across a multiplicity of frequency band signals. Using software (125), for example, a common signal path may be provided for the multiplicity of frequency band signals within a frequency agile radio of a base station by tuning the radio based on a variable feedback through realization of a negative parallel resistance (FDNR). Thus, tuneability of the Q-factor may provide frequency agile radios that include flexible or reconfigurable filters in a base station to serve different frequency bands without changing hardware. In this way, significant savings associated with frequency agility may be obtained.

Abstract: The present invention provides a method and an apparatus for selectively pretuning and updating a phase lock loop, deployed in an integrated circuit including an agile radio, such as a wideband or an ultra wideband frequency agile radio in a telecommunication system, for example, a reconfigurable multiband and/or multistandard mobile communication system. In one embodiment, a phase lock loop may comprise a digital storage having a first desired frequency. An oscillator may provide an oscillator frequency and a frequency generator circuit capable of producing at least one control signal may cause the oscillator to adapt the oscillator frequency based on the first desired frequency in response to a trigger signal. A pretune unit may apply a pretune voltage to a tuning element to cause the oscillator to calibrate the oscillator frequency to the first desired frequency. An output voltage may be added at the output of a loop filter to the pretune voltage to tune the output voltage of the loop filter such that to set the oscillator frequency substantially at the first desired frequency. An update unit may automatically determine whether one or more parameters of a phase lock loop unit have changed to dynamically update the pretune voltage.
