Ultra-high gain audio amplifier


Posted on Feb 13, 2013

Sometimes called the JFET µ-amp, this circuit provides a very low power, high gain amplifying function. Since µ of a JFET increases as drain current decreases, the lower drain current is, the more gain you get

Input dynamic range is sacrificed with increasing gain, however.
