Abstract :
A universal current mode operational transconductance amplifier-capacitor (OTA-C) biquad with three inputs and four outputs employing the minimum of components: only two OTAs and only two grounded capacitors is presented. The proposed circuit offers the following advantageous features: realization of low-pass, bandpass, high-pass, notch; and all-pass signals from the same simple configuration, employment of two grounded capacitors ideal for integration and low-sensitivity performance
