The circuit belоw is а vаriаble gain amplifier. Suppоse Rf =1000 Ohm, JFET has the threshоld voltage of -0.3V and corresponding resistance shown in the table, what is the maximum and minimum gain for this amplifier as the control voltage is varied from 0 to Vth? DC control voltage of JFET (V) Resistance of JFET (Ohm) 0.0 200 -0.3 infinite
