Amplifier noise, LNA, mixer, noise optimization, and PHS.
Noise in CMOS low noise amplifier (LNA) is analyzed in detail, including channel noise and induced gate noise in MOS devices. A new analytical formula for noise figure is proposed including the effects of distributed gate resistance and intrinsic channel resistance. Power constrained noise optimization is performed. A design of CMOS PHS front-end using this technique is also included.
