//Initialisation
Ie=1.02*10**-3
RB=910*10**3 //resistance in ohm
hfe=100 //HFE parameter of the transistor
RC=4.7*10**3 //resistance in ohm
hoe=10*10**-6 //HOE parameter of the transistor
//Calculation
gm=40*Ie
hie=hfe/(40*Ie) //HIE parameter of the transistor
av=-gm*RC/((hoe*RC)+1) //small signal voltage gain
ri=(RB*hie)/(RB+hie) //Input Resistance
a1=1/hoe
ro=(RC*a1)/(RC+a1) //Output Resistance
//Results
