摘要
The present invention relates to a filter tuning circuit, a multi-stage filter tuning circuit and a method for tuning filter. According to an embodiment of the present invention, the filter tuning circuit comprises: a filter block for filtering and outputting frequency for inputted signals according to frequency tuning based on feedback control signals after receiving the inputted signals; a power detector for extracting the strength of outputted signals of the filter block and outputting signals for producing feedback control signals; and a digital conversion block for receiving signal output of the power detector, producing the feedback control signals converted into digital and giving feedback to the same into the filter block. Additionally, the multi-stage filter tuning circuit and the method for tuning filter are provided.;COPYRIGHT KIPO 2015
