Abstract (en)
[origin: WO2006128075A1] Calibrating a filter (114,116) is disclosed. The filter (114,116) is reconfigured as an oscillator during calibration. Switches (swl,sw2 ) and/or other implementations of reconfiguring a filter are used to reconfigure the negative feedback loop of the filter to a positive feedback loop. The oscillation parameters are then measured (106, ( 300 ) to adjust the components of the filter (cl-c4) to achieve an oscillation that corresponds to a desired filter characteristic.
