所以本篇論文主要研究於IEEE 802.11 b/g的無線網路接收機部分，內容主要包含高頻積體電路理論、低雜訊放大器、混波器，使用 TSMC 0.18um 1P6M CMOS製程。低雜訊放大器部份透過電路技巧使用了current reuse的架構，可以在相同的功率消耗之下，能有比較好的效能，另外還設計了可以調整增益的機制在裡面，透過電壓或電流偏壓的控制，可以改變電路本身的特性。混波器採用了次諧波混波器(Subharmonic Mixer)，這種架構應用於直接降頻架構可以減少DC Offset的現象，而且也設計了一個控制輸出電壓的機制，它不僅可以維持輸出電壓的準位，而且還可以透過它控制混波器的增益以及線性度。
This thesis major study in IEEE 802.11 b/g for WLNA Receiver . The contents include RF Fundamental, Low Noise Amplifier(LNA),and Mixer.
We use the TSMC 0.18um 1P6M CMOS process to implement our circuit.
The low noise amplifier uses the technology called current reuse. Since PMOS devices in scaled technology, the idea is to realize the input stage shunting an inductively degeneration NMOS stage with a PMOS one. In this way, due to the inherent current reuse, the performances can be improved using the same power consumption. Besides the current reuse, we utilize control gain to change current or voltage. Thus, it can change the circuit's performance.
A active double-balance even harmonic mixer is introduced. This architecture can avoid the problem of DC Offset in direct conversion. It not only haves the control gain to keep the voltage of output circuit, but also can vary gain and linearity of the mixer.
