Abstract

The noise optimization design of the CMOS LNA is important in communication IC. The conventional noise optimization method for L-degeneration cascoded LNA with noise mainly from active device loses the validity as the operating frequency increasing. In this paper, we present a novel noise optimization with gain matching design method for LNA with fully considerations of noise sources including the induced gate noise and the loss of gate inductor. The gate inductor will be an important issue when its quality factor is less than 20.
