dc.description.abstract | 一個包含正交調變器、可變增益放大器
與晶片上之輸出變壓器的5.8GHz 發射機前
端以CMOS 0.18-um 製程在本計畫中實現。
該正交調變器採用交差耦合式微混波器架
構,在輸入250mVpp 的信號下可達成32dB
的第三次項非線性抑制。利用4-bit 的控制單
位所設計出的16 階-對數線性-增益變化,可
達成總共27dB 的輸出動態範圍。單端型式輸
出則藉由一個晶片上之3:1 變壓器來完成,
而輸出匹配電路也因此被簡化。 | zh_TW |
dc.description.abstract | A 5.8 GHz transmitter front-end comprising a
quadrature modulator, a variable gain amplifier
and an on-chip output balun in CMOS 0.18-um
technology is presented. The quadrature
modulator adopts cross-coupled type
micro-mixer, and the measured 3rd-oder
rejection is 32 dB under input voltage swing of
250 mVpp. With four-bit control words, a
16-step linear-in-dB output power is realized to
achieve a dynamic range of 27 dB. A
single-ended type output is accomplished by an
on-chip 3:1 transformer and the output
matching network is therefore simplified. | en |
