本次設計了兩種不同電流控制模式的降壓轉換電路。提出的第一個轉換器採用新型的積分式電流感測電路並運用磁滯控制來縮短暫態響應時間,積分式電流感測可以提高整體轉換效率與減少功率上的消耗。第一顆晶片採用TSMC 0.18 um 1P6M,面積為1.107x 0.851〖mm〗^2,其輸入為3.3V,晶片輸出範圍由1V至2V,峰值效率在輸出為2V負載電流為300mA時得到90.6%。
第二顆提出的轉換器是採用自適應導通時間控制技術的仿DCR電流感測降壓轉換器。電路控制為自適應導通時間控制並以仿DCR電流感測電路以作為電流模式獲取電流訊號的調節器。晶片採用TSMC0.18um1P6M,面積為1.128x 0.91434 〖mm〗^2,其輸入範圍由3V至3.3V,晶片輸出範圍由1V至2V,峰值效率在輸出為2V負載電流為300mA時得到90.63%。

The thesis proposed two different current-sensing circuits and different controlled-mode buck converters. The first converter proposed uses a new integral current sensing circuit and uses hysteretic-controlled to acceleration transient response time. The integral current sensing can improve the overall conversion efficiency and reduce power consumption. The first chip uses TSMC 0.18 um 1P6M, with an area of 1.107x 0.851〖mm〗^2. It’s input is from 3.3V, and the chip output range is from 1V to 2V. The peak efficiency is 2V at the output and the load current is 90.6% is obtained at 300mA.
The second proposed buck converter is a pseudo-DCR current sensing buck converter with adaptive on-time control technology. The circuit control is adaptive on-time control and uses pseudo-DCR current sensing as a regulator for obtaining current signals in current mode. The chip adopts TSMC0.18um1P6M, the area is 1.128x 0.91434 〖mm〗^2, the input is from 3.3V, the peak efficiency is 2 at the output and the load current is 300mA obtained 90.63%.
