Push-pull amplifier having inductive common mode decoupling
Abstract:
A push-pull amplifier is provided for amplifying an input signal, having first and second amplifier elements. Each of the amplifier elements has a current-emitting electrode, a current-collecting electrode, and a current-controlling electrode. The input signal is supplied to the current-controlling electrodes of the amplifier elements via a respective input connection and a respective input inductor arranged between the respective input connection and the respective current-controlling electrode. The current-collecting electrodes are connected via a respective supply inductor having a common supply voltage. The current-emitting electrode of each amplifier element is connected to the current-collecting electrode of the other amplifier element via a respective capacitor. The current-emitting electrodes are connected to output connections on which the output signal can be picked up, and to a reference potential via a respective output inductor. The supply inductors of the amplifier elements are inductively coupled to the input inductors and the output inductors of the respectively other amplifier element.
