碩士 === 國立交通大學 === 電信工程系所 === 97 === This thesis is divided into two parts. The first part is about flicker noise improvement for RF CMOS active mixers. Flicker noise in the mixer of a zero IF or low IF wireless receiver can compromise overall receiver sensitivity. Improving the flicker noise corner can increase the SNR. We choose a TSMC 0.18um CMOS technology and TSMC 0.13um CMOS technology to implement low flicker noise active mixer. The other part demonstrates 60GHz 4x subharmonic diode mixers. The object of the design is to realize a technique of flip-chip. The advantages of this technique are the elimination of heat effects and the inductance effects due to bond wires. 60GHz CPW 4x subharmonic mixer and 60GHz CPW 4x subharmonic mixer and amplifier for up conversion are designed and implemented by using WIN 0.15μm PHEMT technology process .
