本論文探討漣波控制升壓穩壓器以及適用於漣波控制之電流感測技術之研究並且進行晶片實作。根據此研究，提出兩種合成模式之電流感測技術並將其實現於遲滯控制升壓穩壓器上，並以晶片實作驗證其設計。
第一個晶片實作是以斜波仿真迴授之電流感測技術實現兩種架構，第一種為不具備電壓平方迴路之遲滯升壓穩壓器，經由此合成模式之電流感測技術，可以實現不需經由迴路補償之遲滯控制升壓穩壓器。另一個實現之架構為具備電壓平方迴路之遲滯升壓穩壓器，以斜波仿真迴授電流感測技術，實現結合了電壓平方之遲滯控制，使其能有較佳的電壓調節率與暫態響應能力。由量測結果顯示，此兩種架構都能操作在輸入電壓5V、輸出電壓12V及負載電流0-300mA的系統規格中。而在幾乎全負載範圍內都能達到80%以上之效率，最高效率為92.1%。在結合電壓平方之遲滯控制架構中，於100-300mA的負載電流變化，可以達到更快的回復時間。
本論文所提出的第二個電流感測技術稱為漣波電流重建技術，並用此電流感測技術實現在合成模式遲滯控制升壓穩壓器上。經由此漣波電流重建技術，可以使此升壓穩壓器同樣的不需要補償迴路便能穩壓。且能達到更低電路與元件成本的優勢。系統規格同樣能操作在輸入電壓5V、輸出電壓12V及負載電流0-300mA中，在幾乎全負載範圍內同樣都能達到80%以上之效率，而最高效率為92.3%。

This thesis focuses on the study and design of ripple-based control boost regulators and current-sensing technique applicable for ripple-based control with chip implementation. According to the study, this thesis proposed two synthetic-mode current-sensing techniques in hysteretic control boost regulators and with chip verifications.
First, an Emulated-Ramp Feedback (ERF) current-sensing technique is used to implement two structures. One is "a hysteretic boost regulator without V2 loop". By ERF synthetic-mode current-sensing technique, a hysteretic control boost regulator without loop-compensation is presented. The other one structure named "a hysteretic boost regulator with V2 loop" is also proposed. This structure combined V2 and hysteretic control with ERF current-sensing technique to achieve better output voltage regulation and transient speed. As shown in experimental result, these two structures can be operated in a 0-300mA wide load current range at supply voltage of 5V and output voltage of 12V. The transfer efficiency is larger than 80% at almost full load range. The peak transfer efficiency is 92.1%. In “a hysteretic boost regulator with V2 loop” structure, the transient response recovery time is much faster.
The second current-sensing technique proposed by this thesis is called Ripple-Current Reconstruction technique. And this current-sensing technique is used to implement a synthetic-mode hysteretic control boost regulator. By Ripple-Current Reconstruction current-sensing technique, neither a loop-compensation is needed to stabilize the system in this proposed regulator. And a much lower circuit and passive component cost is achieved in this proposed design. This proposed system can be also operated in a 0-300mA wide load current range at supply voltage of 5V and output voltage of 12V. The transfer efficiency is larger than 80% at almost full load range, and the peak transfer efficiency is 92.3%.
