Fet Microphone Mixer Circuit


Posted on Apr 20, 2012

A JFET transistor-is used as a high-to-low impedance converter and signal mixer. Input impedance is approximately 50.0 kQ but it can be increased by increasing R5 to R8 as high as 10 . Output is about 2 kQ, but it can be increased or decreased by changing the value of i10.
