摘要：A method and apparatus for direct tuning of a component embedded within an integrated circuit includes processing that begins by providing a plurality of frequency dependent control input signals to an input of the integrated circuit. The processing continues for each of the plurality of frequency dependent control input signals by incrementally adjusting the power level of each frequency dependent controlled input signal until the signal strength of an output of the integrated circuit is at a desired signal strength level. The corresponding power level is recorded to produce an adjusted power level for the frequency dependent control input signal. The adjusted power level of each of the plurality of frequency dependent control input signals is plotted to produce a signal strength to frequency relationship. The processing continues by comparing the signal strength to frequency relationship with a desired signal strength to frequency relationship. The process then continues by tuning the component such that the signal strength to frequency relationship more closely resembles the desired signal strength to frequency relationship when the comparison was unfavorable.
