The year 2018 marked 100 years since the introduction of a class of oscillatory circuits called Colpitts oscillators. Few other electronic circuits have survived for such a long time and affected the electronic technology as the Colpitts oscillator. Today, Colpitts oscillators are found in both communication systems and digital circuits as clock and frequency generators. In this paper, we provide a comprehensive overview over the development of the Colpitts oscillator, from the simple vacuum tube oscillator patented by Colpitts in 1918, to state of the art MEMS oscillators operating at high GHz region in today?s modern electronics. We review different types of Colpitts oscillators, including singleended, differential, complementary, gm-boosted and introduce a timeline for the development of these circuits.

Colpitts 振荡器 100 年：常见振荡器电路拓扑的本体论回顾

2018 年是自推出一类称为 Colpitts 振荡器的振荡电路以来的 100 年。很少有其他电子电路能像科尔皮兹振荡器一样存活这么长时间并影响电子技术。今天，在通信系统和数字电路中都可以找到 Colpitts 振荡器作为时钟和频率发生器。在本文中，我们全面概述了 Colpitts 振荡器的发展，从 Colpitts 于 1918 年获得专利的简单真空管振荡器到当今现代电子产品中在高 GHz 区域运行的最先进的 MEMS 振荡器。我们回顾了不同类型的 Colpitts 振荡器，包括单端、差分、互补、gm-boosted，并介绍了这些电路的开发时间表。
