摘要：

In this paper, a bandpass filter with controllable cutoff frequency is designed by using current mode synthesis method which is good to design the low-voltage and low-power filter. The designed bandpass filter is composed of cascade connection between 3rd Butterworth highpass filter and 3rd Chebychev lowpass filter. And as a core circuit in the current-mode filter, a current-mode integrator and differentiator are designed and apply to designing filters. The cutoff frequency of the designed 6th bandpass filter can be controlled to 120kHz similar to 54MHz according to control voltage, 0.7V similar to 1.5V.
