Abstract: A transformer is provided. The transformer includes at least one first primary turn; at least one second primary turn; and a first secondary turn and a second secondary turn. The first secondary turn and the second secondary turn are arranged laterally between the at least one first primary turn and the at least one second primary turn. The first secondary turn and the second secondary turn are arranged one above the other.

Abstract: An amplifier includes a first lower active sub cell and a second lower active sub cell, each comprising an input terminal and an output terminal, wherein the input terminals of the lower active sub cells are connected to the amplifier input and the output terminals of the lower active sub cells are not shorted. Furthermore, the amplifier includes a first upper active sub cell and a second upper active sub cell, each including a biasing terminal, wherein the input terminals and the output terminals of the upper active sub cells are coupled between the output terminals of the lower active sub cells and the amplifier output. The amplifier includes a bias controller configured to provide a first biasing signal to the first upper active sub cell and a second biasing signal to the second upper active sub cell based on an output power of the output signal.

Abstract: A cascode circuit includes a first transistor and a second transistor. The first transistor and the second transistor are connected to make a cascode. In addition, the circuit has a block capacitance which is connected between a control terminal of the second transistor and a source terminal of the first transistor. In addition, the circuit has a feedback element which is connected between a drain terminal of the second transistor and a control terminal of the first transistor.
