Direct neutralization

[Kevin Weddle]

Some transistors have a collector to base capacitor, but no inductor. Does that mean a single capacitor is acceptable and that sometimes neutralization is better? Would it depend on the frequency?

What are you talking about?

Please post a schematic.

Inductors can self resonate because of their interelctrode capacitance. Neutralization is an attempt to neutralize interelectode capacitance with an inductor. Typical of higher frequency circuits. But their performance is bad due to poor engineering and poor production. Almost they don't work but minimal.

Please post a link to an article, I Googled and couldn't find much.

The only free article I could find is dated 1955 and is about values (toobes as they say in America).
