Jfet Variable Gain Amplifier at Russell Stinson blog

Jfet Variable Gain Amplifier. The pots theoretically set the minimum resistance for the jfet attenuator and the gain for the amplifier and i haven't found an. Is a rough approximation only and can be used for rs>>1/gm only (without any bypass capacitor). This device is known as a. This restriction applies also to the bjt case. This article on fets for voltage controlled circuits will cover fet modulator circuits and variable gain amplifier (vga). Such a device has a gain that is controlled by a dc voltage or, more commonly, a digital input. The gain of the opamp stage is determined by the transconductance of the jfet and r4, and r2 only affects the gain by varying the transconductance a little.
