<p>Aspects of the disclosure can provide a bandpass transconductance amplifier that can include a minuend transconductance amplifier that converts a voltage signal to a first current and a subtrahend transconductance amplifier that converts the voltage signal to a second current having substantially the same amplitude as the first current but opposite polarity in both a first and a second stopband. The second current can have a substantially smaller amplitude than the first current in a passband. The disclosed bandpass transconductance amplifier can also include a controller that can tune the passband and the stopbands and a summing circuit that can add the first current and the second current.</p>
