Abnormal oscillation

In electrical and electronic circuits, oscillations that were not originally expected may occur at certain frequencies due to design flaws or wiring defects, which can interfere with functionality. In amplification circuits, this may happen if part of the output feeds back into the input and is repeatedly amplified. Accurate design and wiring are important to prevent abnormal oscillation. As a countermeasure when it occurs, changing the CL value of the component is one method. This phenomenon is also called spurious oscillation.
