I did the calculation as follows:
\[ A_{v_L}=\frac{R_L//R_C}{r_e}=I_C\frac{R_L//R_C}{V_T}=508mA\cdot\frac{5\Omega}{26mV}=97.69 \hspace{2mm}V/V \]
According to measurements:
\[ A_{v_L}=\frac{289mV}{40mV}=7.25 \hspace{2mm}V/V \]
I increased the signal frequency and the capacitors value to...
Hello.
Simulation results:
IC=508mA; IE=518mA; IB=9.97mA
VCE=19.89V; VCB=-18.92V; VBE=0.97V
VRL(rms)=289.236mV
I know what is re in the expression.
Why is the C2 polarity wrong? The voltage at that point never reaches 0, it is always positive.
I did the measurements like this...
Hello Guys.
I have tried to calculate the voltage gain of the following circuit without measuring, only with the values that I have of the components. There are some formulas in texts like Sedra and Boylestad, but they are nowhere near what I actually measure with the multimeter. The circuit is...
