本文首先表明，各种著名的简单的振荡器电路，通常单独分析，基本上是相互等效的，如果某些合理的假设，并赞赏这一事实简化了设计问题。讨论如下关于C类振荡器和困难相结合的高效率与晶体管参数的独立性令人满意的程度。避免吱吱声的问题也被认为是。然后描述了一个简单的推挽式高效率振荡器，其中每个晶体管在其整个180°导通角内都有基本恒定的电流流过。该振荡器被认为具有所需特征的独特组合。另一个不寻常的高效率振荡器，这是更详细的比前一个，但在某些方面具有优势。最后，本文描述了振荡器的基础上的“长尾对？电路.该振荡器非常易于设计和制造，适用于高效率并不重要的应用。它可以提供正弦波或方波，或两者兼而有之。
The paper begins by showing that various well-known simple oscillator circuits, usually analysed separately, are essentially equivalent to one another if certain reasonable assumptions are made, and appreciation of this fact simplifies the design problem. A discussion follows concerning class-C oscillators and the difficulty of combining high efficiency with a satisfactory degree of independence of transistor parameters. The problem of avoiding squegging is also considered. A simple push-pull high-efficiency oscillator is then described, in which substantially constant current flows in each transistor for the whole of its 180° conduction angle. This oscillator is believed to possess a unique combination of desirable features. Another unusual high-efficiency oscillator is then presented, which is more elaborate than the previous one but which has advantages in certain respects. The paper ends with a description of an oscillator based on the `long-tailed-pair? circuit. The oscillator is exceptionally easy to design and make, and is suitable for applications where high efficiency is not important. It can supply either a sine wave or a square wave, or both.
