| dc.description.abstract | 本論文分為兩個部分，第一部分是闡述一個直流直流轉換器，以遲滯預測電壓控制技術來降低暫態的電壓變化以及加速暫態響應。當系統是穩態時，這個技術利用雙級錯誤放大器做補償，提高相位邊界，當暫態發生時，會切換到遲滯模式加速暫態響應。這個晶片是以台積電 0.35μm 2P4M 3.3V/5V Mixed Signal CMOS 製程製作。依據實驗結果，本晶片操作再切換頻率為1MHz，暫態回復時間為8μs，當負載電流為200mA時，最高效率為89.2%。晶片總面積約為2.85 mm2。第二部分是闡述一個使用成對匯流排調光技術與以連續漸進暫存器控制適當的結束時間技術的發光二極體驅動器。 Twin Bus 調光技術是利用兩個電壓源降低功率電晶體上的跨壓，得到較高的效率。以連續漸進暫存器控制適當的結束時間技術是用來計算精確的電感電流。使發光二極體的亮度穩定。這個晶片是以0.25-μm CMOS High Voltage 2.5/5/7/12/20/24/40/45/60V Mixed-Signal 1P5M 製程製作。由模擬的結果可知，發光二極體驅動器效率可超過93%，安定時間為3μs。 | zh_TW |
| dc.description.abstract | The thesis can be divided two parts. The first one presents a DC-DC converter uses the Hysteresis Prediction Voltage Control (HPVC) to suppress the transient overshoot voltage and speed the transient response. In steady state, this technique utilizes the two-stage error amplifier to compensate and raise the phase margin. When the transient occurs, it switches to the hysteresis mode to speed the transient response. This chip is implemented in a TSMC 0.35-μm 2P4M 3.3V/5V Mixed Signal CMOS process. According to measurement results, this chip operates at 1MHz, transient recovery time is 8μs. The maximum efficiency is 89.2% when load current is 200 mA. The area of this chip is about 2.85 mm2.The second part presents a LED driver with Twin Bus for dimmable lighting and SAR-controlled adaptive off-time technique. Twin Bus for dimmable lighting technique utilizes two voltage sources to reduce the voltage stresses on power transistors and obtain the high efficiency. The SAR-controlled adaptive off-time technique is used to calculate the accuracy inductor current, and the brightness of LEDs is constant. This chip is implemented in a TSMC 0.25-μm CMOS High Voltage 2.5/5/7/12/20/24/40/45/60V Mixed-Signal 1P5M process. According to simulation results, the efficiency of the LED driver is over 93 %, and the settling time is 3 μs. | en |
