A CMOS current-mode continuous-time band-pass filter using the positive feedback Q (quality factor) - enhancement technique is presented in this paper. Q of the proposed filter can be mainly determined by the ratio of the two MOSFETs' transconductances in a Q-setting part, not by the ratio of two capacitance values similar to most of conventional band-pass filters. This filter can realize high Q value in spite of small chip area. Therefore, when higher value of Q is needed, the proposed filter does not need large capacitor which occupies large area on an IC chip. The proposed filter spends smaller chip area than the conventional one under the condition of Q>2. The proposed circuit is simulated by Spectre to confirm its characteristics.
