In this paper, we present a new structure that can process the demodulation without A/D converter. In our method, we have designed an analog decision device using QAM demodulator. Meanwhile, to verify our method, we have also finished a front-end analog Viterbi decoder circuit. Finally, we have designed one analog decision chip and one front-end analog Viterbi decoder chip with UMC 0.18-μm 1P6M CMOS technology. In the decision device chip, it contains 494 transistors, operates to 100Mb/s using a single 3.3-V power supply and consumes 17.46mW. The chip area of the analog decision is about 0.544mm2 . The front-end analog Viterbi decoder chip contains 164 transistors, operates to 100MHz using a single 3.3-V power supply and consumes 22.2mW. The chip area of the analog decision is about 0.286mm2. These chips have the advantages of low-power, small-area, low-cost and are easy to be combined with the RF Front-End Receiver. The new architecture can provide an efficient design for future SOC communications. 李文達 2005 學位論文 ; thesis 56 zh-TW |

碩士 === 國立臺北科技大學 === 電腦與通訊研究所 === 93 === In transitional implementation of wireless communication, it is essential to use a high-speed and high-resolution A/D converter when the receiver signal gets into the digital demodulator and channel decoder.
In this paper, we present a new structure that can process the demodulation without A/D converter.
In our method, we have designed an analog decision device using QAM demodulator. Meanwhile, to verify our method, we have also finished a front-end analog Viterbi decoder circuit. Finally, we have designed one analog decision chip and one front-end analog Viterbi decoder chip with UMC 0.18-μm 1P6M CMOS technology.
