An amplifier (10) having a pair of transistors (CS FET, CG FET) arranged in a cascode amplifier arrangement serially connected to a first voltage source. A DC bias regulator (14) is provided having: a DC bias circuit for producing a reference voltage at a control electrode of a first one (CS FET) of the pair of transistors: and a voltage combiner (18) having a pair of inputs, a first of the pair of inputs being coupled to the reference voltage and a second one of the pair of inputs being coupled to the first voltage source. The DC bias regulator (14) produces a DC bias voltage at a control electrode of a second one (CG FET) of the pair of transistors related to a combination of the reference voltage and the first voltage source. |
