Unformatted text preview: r out = 50k if the transistor has = 0 . 02V 1 ? Use the relations r = 1 + V DS /I D , V DS = 18 I D R D , and r out = r k R D . [ . 189mA , 6 . 67V ] 4. The drain current in an n-channel JFET is given by i D = I DSS (1 v GS /V P ) 2 for v GS > V P and i D = 0 for v GS V p , where I DSS = I DSS (1 + v DS ) . For the n-channel JFET, V P < . Show that the expression for the JFET current can be represented in exactly the same form as that of the MOSFET using the substitution V TO = V P and K = I DSS /V 2 P . 1...
