An OCL amplifier (output capacitor-less amplifier) is any audio amplifier with direct-coupled capacitorless output. Typically, OCL amplifiers can be any of several amplifier classes, and typically have a push-pull output stage. Advantages of OCL amplifiers over capacitor-coupled amplifiers include * Avoiding the cost and bulk of an output capacitor * better immunity to motorboat oscillation * larger output power at very low frequencies and DC Disadvantages of OCL amplifiers include * larger power dissipation and passing DC through the load, in the minority of designs with poorly controlled DC bias point * increased sensitivity of the output DC bias point to process variations, although the last disadvantage is less important for older bipolar processes. ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「OCL amplifier」の詳細全文を読む スポンサード リンク
