Patent ID: 6850117

Claim:
An integrated circuit transistor structure for amplifying a radio frequency signal in a circuit having a reference DC voltage to obtain an amplified radio frequency signal to an output that has a load associated therewith comprising: a first NMOS transistor having a first source connected to ground and a first gate for receiving the radio frequency signal, wherein the first gate is disposed above a first insulator and the first NMOS transistor having a first transconductance and a first breakdown voltage associated therewith; a second NMOS transistor having a second source connected to a first drain of the first NMOS transistor, a second gate connected to the reference DC voltage, and a second drain that provides the output for the amplified radio signal, the load being disposed between the reference DC voltage and the second drain of the second NMOS transistor, wherein the second gate is disposed above a second insulator, the second NMOS transistor having a second transconductance and a second breakdown voltage associated therewith; other CMOS transceiver chip components on the integrated circuit; and wherein the second insulator is thicker than the first insulator so that the first transconductance is greater than the second transconductance.
