Abstract
Embodiments describe a transadmittance amplifier comprising an inverting output port and a non-inverting output port. The transadmittance amplifier comprising a first differential transistor pair having a first transistor comprising an inverting input port. The first transistor is configured to provide an output current to the inverting output port. A second transistor comprising a non-inverting input port. The second transistor is configured to provide an output current to the non-inverting output port. A second differential transistor pair having a third transistor comprising an inverting input port and a fourth transistor comprising a non-inverting input port. A first current source and a second current source. The transadmittance amplifier comprises a first current mirror which is configured to mirror an output current of the fourth transistor to the inverting output port and a second current mirror which is configured to mirror an output current of the third transistor to the non-inverting output port.
