A novel fully integrated voltage mode realization of the Kerwin-Huelsman-Newcomb biquad filter using the Current Differencing Buffered Amplifier (CDBA) is presented. Independent control on the bandwidth, quality factor and gain can be achieved through control voltages. All possible combinations of polarities of the highpass, bandpass and lowpass responses can be obtained. A comparison between previously published implementations of the KHN biquad is included. Analysis of the parasitics associated with the CDBA is presented and compensation techniques are included.
