Which process solves the problem of interelectrode capacitance in the transistor of an RF amplifier?

Neutralization is the process employed to address the issue of interelectrode capacitance in the transistor of an RF amplifier. In RF amplifiers, particularly those using bipolar junction transistors, parasitic capacitances between the various elements (like the base and collector or base and emitter) can lead to unwanted feedback that can cause instability and reduced performance.

Neutralization involves adding an external circuit element, such as a capacitor, that introduces a feedback effect which precisely cancels out the undesired capacitance. This technique helps maintain stable operation by preventing oscillations and improving the amplifier's frequency response.

Compensation, while also a method for improving performance in certain circuits, typically refers to methods used to mitigate the temperature effects or variations in transistor characteristics rather than addressing interelectrode capacitance directly.

Isolation generally refers to techniques used to decouple different parts of a circuit to prevent interference. Stabilization focuses on keeping a circuit’s performance consistent over varying conditions (like temperature and supply voltage) but does not directly deal with the interconnection capacitances that neutralization specifically targets.
