i have serious problem wih ATF36077 ,condition of bias vds=1.5,ids=10 ma,
vgs=-.2,how??????,i obtain the vol of vgs,it was so small,also any buddy give me the wquastions of calculation of rs and rd
thanks so much
hi mazz thanks for reply but i see tha site bofore if u have any paper about supply of atf36077 i will be thanked,how i get vgs=-.2 are u see it is impractical
Put a 20 ohm resistor in series with the source lead to ground, DC ground the gate with an inductor, put 1.7 volts on the drain. Assuming a drain current of 10mA, the SOURCE to GROUND voltage is 0.2 volts AND thus the voltage from GATE to SOURCE is -0.2V (since the gate is grounded). The DRAIN to SOURCE voltage will be 1.5V (1.7V - 0.2V). Try it.
hi i avoid connect source to bias,here my design ,is that design correct,i apporximate that drain current equal source cuurent and gate ground voltage=-.2 plus voltage drop on source resistance
