//Initialisation
rd=50*100*3 //resistance in ohm
gm=72*10**-3 //in siemens
Rd=3.3*10**3 //resistance in ohm
Rs=10**3 //resistance in ohm
//Calculation
av=-Rd/Rs //votlage gain from eq 17.7
b=gm*Rd
c=gm*Rs
av1=-(b)/(1+(c)+((Rd+Rs)/rd)) //voltage gain from eq 17.8
av2=-(b)/(1+(c)) //voltage gain from eq 17.9
//Results
printf("From Eq 17.7, Gain = %.1f\n",av)
printf("From Eq 17.8, Gain = %.3f\n",av1)
printf("From Eq 17.9, Gain = %.3f\n",av2)
