// find output voltage // Electronic Principles // By Albert Malvino , David Bates // Seventh Edition // The McGraw-Hill Companies // Example 10-3, page 325 clear;clc; close; // Given data B=300; R1=10*10^3;// in ohms R2=2.2*10^3;// in ohms Re=1*10^3;// in ohms Rl=10*10^3;// in ohms Rc=3.6*10^3;// in ohms Rg=600;// internal resistance of ac generator in ohms vg=2*10^-3;// in volts Vcc=10;// in volts // Calculations rc=(Rc*Rl)/(Rc+Rl);// ac collector resistance in ohms,Rc||Rl re_=22.7;// ac resistance in ohms Av=rc/re_;// voltage gain zinbase=B*re_;// input impedance of base in ohms zinstage_=(1/R1)+(1/R2)+(1/zinbase);// input impedance of base in ohms zinstage=zinstage_^-1 vin=(zinstage/(Rg+zinstage))*vg;// input voltage in volts vout=Av*vin;// output voltage in volts disp("Volts",vout,"Output voltage") // Results // Output voltage is 165 mVolts.
