plot base current versus base-emitter voltage curves as function of six values of vce for a common emitter bjt in matlab

main.m
% Constants
beta = 100; % common emitter current gain
Vt = 0.025; % thermal voltage

% Base-emitter voltage range
V_BE = linspace(0, 0.7, 100);

% Collector-emitter voltage values
V_CE = [1, 2, 4, 6, 8, 10];

figure;
hold on;

% Loop through each V_CE value
for idx = 1:length(V_CE)
    I_B = (V_BE - 0.7) / 1000; % Base current calculation
    I_C = beta * I_B; % Collector current calculation
    I_E = I_C + I_B; % Emitter current calculation

    % Plot Base current versus Base-emitter voltage
    subplot(2, 3, idx);
    plot(V_BE, I_B);
    title(['V_{CE} = ', num2str(V_CE(idx)), 'V']);
    xlabel('Base-emitter Voltage (V)');
    ylabel('Base Current (A)');
