plot output parametric curves for common emitter amplifier in matlab

To plot the output parametric curves for a common emitter amplifier in MATLAB, you can follow these steps:

1. Define the equations representing the output voltage characteristics of the amplifier. These are typically given by the output voltage as a function of the input voltage and other circuit parameters.

2. Create a range of input voltages that you want to sweep across.

3. Use the defined equations and input voltage range to calculate the corresponding output voltages.

4. Finally, plot the output parametric curves by plotting the output voltage against the input voltage.

Here's a simple example code snippet to demonstrate these steps:

main.m
% Define circuit parameters
Rc = 2; % Collector resistance
Vcc = 10; % Supply voltage
Re = 1; % Emitter resistance
Beta = 100; % DC current gain

Vin = 0:0.1:5; % Input voltage range

% Calculate output voltage using common emitter amplifier formula
Vout = Vcc - Rc./(Rc + Re) .* Vin;

% Plot the output parametric curves
figure;
plot(Vin, Vout, 'b', 'LineWidth', 2);
xlabel('Input Voltage (V)');
ylabel('Output Voltage (V)');

In this example, the output voltage Vout is calculated based on the given common emitter amplifier formula and then plotted against the input voltage Vin.

You can adjust the circuit parameters, input voltage range, and plotting options as needed for your specific common emitter amplifier circuit.
