Modified buffered transconductance amplifier for analog signal processing

A new active element for analog signal processing, namely the current inverter buffered differential input transconductance amplifier (CIBDITA), is proposed. It combines some features of the well-known current differencing buffered and transconductance amplifiers, simplifies their current input stage, and increases their universality by introducing an additional voltage-type input. The usefulness of this new element is demonstrated on the example of a 2^nd-order filter which employs only one active element, two grounded capacitors, and one resistor.
