Re: 2N5109 amp directly biased with ZD
|
Zeners are also good noise generators.? It could work well, but must be well filtered.

Hi All,
?
I saw an interesting article.
an amplifier using a 2N5109 at the bottom of this page.
It has a 3.3V zener diode and a 3.3k resistor to make a bias voltage.
It looks simple and stable, seems to work well in LTSPICE simulations.
I have a question.
I have never seen a direct bias style like this.
Is there any problems?
?
