//Variables
VCC = 10.0 //Source voltage (in volts)
RC = 5.0 * 10**3 //Collector resistance (in ohm)
RB = 1.0 * 10**6 //Base resistance (in ohm)
RE = 1.0 * 10**3 //Emitter resistance (in ohm)
RL = 10.0 * 10**3 //Load resistance (in ohm)
beta1=100.0;beta2=100.0;
//Calculation
IE = VCC /(RE + RB/beta1) //Emitter current (in Ampere)
r1e = 25.0/IE * 10**-3 //a.c. emitter diode resistance (in ohm)
Ri1 = beta1 * r1e //Input resistance of first stage (in ohm)
Ri2 = beta2 * r1e //Input resistance of second stage (in ohm)
Ro1 = RC * Ri2 / (RC + Ri2) //Output resistance of first stage (in ohm)
Ro2 = RC * RL / (RC + RL) //Output resitance of second stage (in ohm)
Av1 = Ro1 / r1e //Voltage gain of first stage
Av2 = Ro2 / r1e //Voltage gain of second stage
Av = Av1 * Av2 //Overall voltage gain
Gv = 20 * log10(Av) //Overall dB voltage gain
//Result
