| dc.description.abstract | Since the rapid development of the CMOS technology, a RF analog front-end receiver can be integrated on a single chip. This thesis introduces a highly integrated RF receiver front end for Bluetooth system. This front-end design composed of low noise amplifier, two downconversion mixers, passive polyphase with buffers, and active polyphase filter. It receives the 2.4GHz desired high frequency signal ,and then translates it to 700KHz. Besides downconversion, it also needs image rejection by active polyphase filter. At last, it generates I_Q path and feed I_Q to baseband. Before I_Q fed into baseband, it needs AGC to reduce the dynamic range (44dB) and SAW filter as channel select filter. The design of AGC is not included in the thesis.
The whole analog front-end is implemented by using TSMC 0.6um SPTM standard CMOS technology under 3.3V power supply. It has 35.8dB cascaded gain, 15.2dB noise figure, 24dB image rejection ratio, -14dBm IIP3. The total RF front-end power consumption is about 250mW. The total chip area is . | en_US |
