1db compression point
I am working on the buffer operation @ 2.5GHz and 5GHz. The 1dB compression point is 10dBm. I tried to increase overdrive voltage or gm to improve the P1dB, however, it stops at 8dBm. I do not know how to improve it. Any one can give me some idea. Right now, i am using cascode topology, loading a inductor. Is there any other topology has better linearity?
Thanks.
