| Summary: | A four-inputs and two-outputs voltage-mode universal biquadratic filter using only two operational transconductance amplifiers (OTAs) and two capacitors is presented. The new circuits offer several advantages, such as employing the minimum number of active and passive components (two OTAs and two capacitors); the versatility to
synthesize highpass, bandpass, lowpass, notch and allpass responses; high input impedance and employing only grounded capacitors for bandpass and lowpass filter realizations; some derived filter types enjoy the availability of one more simultaneously output filter response and good sensitivities performance |
