A trimming technique for the active RC filter is proposed. This method requires only once of the measurement of initial filter response to find the trimming resistance values. The features of this method are that the roughly selected initial element values are acceptable and the resulting trimming resistance values always increase, which is convenient for the usual laser trimming system.
