Amplifier bias circuit, method for biasing an amplifier and integrated circuit comprising an amplifier bias circuit

摘要

An amplifier bias circuit connectable to an amplifier device, comprising a first sensor device for sensing a first amplifier characteristic and for providing at a first sensor output a bias signal related to the first amplifier characteristic. The circuit further comprises a second sensor device for sensing a second amplifier characteristic and for providing at a second sensor output a bias signal related to the second amplifier characteristic. The first sensor output and second sensor output are each connected to an amplifier connect connectable to a bias input of said amplifier device.
