Noise generator


Posted on Jul 3, 2012

The zener breakdown of a transistor junction is used as a noise generator. The breakdown mechanism is random and this voltage has a high source impedance. By using the op amp as a high input impedance, high ac gain amplifier, a low impedance, large signal noise source is obtained

The 100K potentiometer is used to set the noise level by varying the gain from 40 to 20 dB.
