... In JFET the drain source conductance gd = Id/Vds for small values of Vds which may be expressed as gd = gdo [ 1-( VgsVp)1/2 ] where gdo is the value of drain conductance when the bias voltage Vgs is zero. The variation of the rd with vgs can be closely approximated by rd = ro / 1- KVgs ro – drain re ...
