碩士 === 國立暨南國際大學 === 光電科技碩士學位學程在職專班 === 102 === This thesis mainly utilizes standard TSMC 180nm CMOS process technology to implement up-conversion mixers for W-band. Constituted by the following research topics: In the paper, a 22~26 GHz low noise amplifier is designed for K-band system. For the sake of reducing chip size and cost, we design a two stage cascade amplifier. In the first stage we use a common source circuit. In order to get sufficient gain, we use a cascode circuit in the second stage. Then we use transmission line technique at the input and output term to achieve flat high gain (S21), and better “S-Parameter” performances. Finally, the current sharing technology to reduce the power dissipation in the second stage of the architecture manipulation
