Abstract

This study describes injection locking phenomena for multi-frequency generator design. For the design of the multi-frequency generator, we describe the basic theory of injection locking phenomenon and conduct a single injection locking experiment based on it. The experiments was conducted by applying injection signals that vibrates consistently to oscillators which vibrates unstablely compared to injection signals. Injection signal was applied using a Howland current source and circuit was designed using a Colpitts oscillator. The results of the experiment showed that each oscillator oscillates reliable when injection signals(840kHz, 500kHz) are injected. Through the results of a single injection locking experiment, it is confirmed that injection locking phenomena can be applied in the design of the multi-frequency generator.

본 논문에서는 다중 주파수 발생기의 설계를 위한 단일 인젝션 락킹 현상에 대한 연구를 진행한다. 다중 주파수 발생기 설계를 위하여 인젝션 락킹 현상에 대한 기본적인 이론을 서술하고 이를 토대로 단일 인젝션 락킹 실험에 대하여 서술한다. 실험은 인젝션 신호에 비해 불안정하게 진동하는 발진기에 일정하게 진동하는 안정된 신호인 인젝션 신호를 인가하는 방식으로 진행하였다. 인젝션 신호는 홀렌드 전류원을 사용하고 콜피츠 발진기를 사용하여 회로를 구성하였다. 실험결과 각각의 인젝션 신호(840kHz, 500kHz)를 주입하였을 때 각각의 발진기가 안정하게 진동하는 것을 확인하였다. 위의 단일 인젝션 락킹 실험결과를 통하여 다중 주파수 발생기 설계에 인젝션 락킹 현상을 응용 할 수 있음을 확인하였다.
