Claim 0:
1. An amplifier, comprising:
an input transformer including a first coil, a second coil, and a third coil, the second coil being coupled to an input node configured to receive an input signal;
a first transconductance transistor having a gate coupled to the input node through the second coil and having a source coupled to the third coil;
an output transistor;
an output transformer including a fourth coil coupled to a source of the output transistor; a fifth coil coupled to a gate of the output transistor; and a sixth coil coupled to a drain of the output transistor; and
a first cascode transistor coupled between a drain of the first transconductance transistor and the fourth coil.
