从最基本层面来看，振荡器电路需要由一个谐振电路、一个晶体管放大器和一个反馈电路组成。

1、Tank Circuit 谐振电路

The tank circuit consists of an inductance L connected in parallel with capacitor C. The values of these two components determine the frequency of the oscillator circuit and hence this is called as Frequency determining circuit.
谐振电路由与电容器C并联的电感L组成。这两个分量的值决定了振荡器电路的频率，因此这被称为频率确定电路。

2、Transistor Amplifier 晶体管放大器

The output of the tank circuit is connected to the amplifier circuit so that the oscillations produced by the tank circuit are amplified here. Hence the output of these oscillations are increased by the amplifier.
谐振电路的输出连接到放大器电路，以便谐振电路产生的振荡在这里被放大。因此，这些振荡的输出由放大器放大。

3、Feedback Circuit 反馈电路

The function of feedback circuit is to transfer a part of the output energy to LC circuit in proper phase. This feedback is positive in oscillators while negative in amplifiers.
反馈电路的功能是将部分输出能量以适当的相位传输到LC电路。该反馈在振荡器中为正，而在放大器中为负。
