Abstract
A tunable, linear operational transconductance amplifier includes a differential voltage to current conversion unit adapted to generate first and second output signals at respective first and second output nodes responsive to first and second differential input signals. A first current amplification unit is adapted to generate a third output signal responsive to the first output signal and first and second control signals. A second current amplification unit is adapted to generate a fourth output signal responsive to the second output signal and the first and second control signals.
