Classification: CPC H | IPC H

Claim 14:
15. A method for biasing an amplifier, the method comprising:
providing an amplifier comprising an input transistor and a plurality of cascode transistors comprising a first cascode transistor coupled to the input transistor and remaining one or more cascode transistors;
coupling a plurality of series-connected resistors between a varying supply voltage to the amplifier and a reference ground, thereby obtaining a plurality of nodes of the series-connected resistors;
coupling a substantially fixed reference supply voltage to a first node of the plurality of nodes,
coupling a gate of the first cascode transistor to a respective node of the plurality of nodes that is arranged between the first node and the reference ground, and
coupling gates of the remaining one or more cascode transistors to respective nodes of the plurality of nodes that are arranged between the varying supply voltage and the first node.
