dc.description.abstract | 隨著 VLSI技術的演進,類比電路已經被實現在更低提供壓及小晶 技術的演進,類比電路已經被實現在更低提供壓及小晶 片面積。 三角積分 類比 數位 轉換器 藉由過取樣 (oversampling)與雜訊移頻 與雜訊移頻 (noise-shaping)的方式 ,能夠輕易達到高解析度 能夠輕易達到高解析度 。 本論文 經由台積電的 0.18微米 設計與 製程 實現 一二階 三角積分 調變 器。在輸 入開關 上採用拔靴式並用最佳化過的單級正回授放大器來減低功耗 ,所設 計之 三角積分類比數位轉換調變器 經模擬後 的訊號雜比為 97dB、1V 供電壓 下功耗為 26uW,晶片總面積 晶片總面積 0.86x0.86 mm2(含 I/O pad)。 | zh_TW |
dc.description.abstract | With the scaling down of VLSI technology, analog circuits are implemented under lower power supply and smaller chip area. Delta-Sigma modulator is able to achieve high resolution with oversampling and noise-shaping techniques. This work presents the design and implementation of a second order delta-sigma modulator with TSMC 0.18 um process. The input switches are bootstrapped switches and a optimized single-stage operational transconductance amplifier (OTA) with positive feedback is used to minimize power consumption. The post-layout simulation shows that the modulator is able to achieve a SNR of 97 dB with 26 uW power consumption under 1 V power supply. Chip area is 0.86x0.86mm2. | en_US |
