ABSTRACT:
In a bipolar OTA (operational transconductance amplifier) including a plurality of triple-tail cells, each of the plurality of triple-tail cells comprises a transistor pair of first and second transistors (Q1 and Q2) forming a differential input/output pair and a third transistor (Q3) applied with a control voltage (V.sub.C). The transistor pair and the third transistor are driven by a common tail current. The OTA has transistors (Q7 and Q8) for applying a dc offset voltage to an input signal of the differential input/output pair. The plurality of triple-tail cells have outputs connected in parallel.
