Abstract:
A circuit for use as an amplifier comprising:first and second input terminals configured to receive first and second input signals;first and second active devices each having first and second terminating regions and a control region by which it is capable of being directed to provide a conductive path between the first and second terminating regions, wherein the control region of the first active device is coupled to the first input terminal and the control region of the second active device is coupled to the second input terminal;first and second output terminals at which first and second output signals are provided, wherein the first output terminal is coupled to the first terminating region of the first active device and the second output terminal is coupled to the first terminating region of the second active device;a first decoupling network connecting a supply of fixed polarity voltage that is not otherwise connected in the circuit to the first output terminal and to the second terminating region of the second active device; anda second decoupling network connecting the supply of fixed polarity voltage to the second output terminal and to the second terminating region of the first active device.
