A JFET has the following ratings: gm0 = 4000µs at VGS off ( ) = 6 Volts and gm0 = 2000µs at VGS off ( ) = 2Volts. The component is used in a common source amplifier with values of RD = 3.3 Kohm, RL = 4.7 K ohm,and VGS = 750 millivolts to 3.5 Volts. Compute the maximum and minimum values of the amplifier voltage gain Av for the given circuit.
