RedAbstract approved: acted for Privacy / vavia J. All StOt A MOS biquadratic (biquad) filter employing the switched-current technique is reported. The circuit uses current-mode processing which can offer wide bandwidth, low voltage operation, and can be implemented with standard CMOS technology. Examples of lowpass, highpass, and bandpass filters are given which illustrate the synthesis procedures and the versatility of the filter topologies.
