碩士 === 國立中興大學 === 電機工程學系所 === 94 === This thesis divides into two parts. The first part is to analyze the parasitic effect of spiral inductor for RFIC applications. We use the equivalent circuit to analyze its behaviors such as the Q value varies with varied width of the inductor widths. The coupling effect influenced by the underpass in different metal layer. To investigate the substrate effect with distance. To study the inductor behaviors with dummy metal under spiral inductor in layout. To discuss high coupling transformer and the RF MEMs switch. The second part uses foundry 0.18um CMOS process to design a down conversion mixer for 802.11b/g WLAN 2.4GHz ISM band applications. The RF frequency is at 2.4GHz, LO frequency is at 2.2GHz, and IF frequency is at 200MHz. We used a transmission gate and a transconductor amplifier to combine a low power mixer.
