Download Electronics and Circuit Analysis using Matlab PDF ebook free by John O.Attia. This book on electronics circuit analysis teaches how to solve electronics circuit problems using Matlab. This matlab book contains tutorials on transient analysis, DC analysis, AC analysis, Fouier analysis among many basic analysis. Other subject that is taught by this book is the diode, semiconductors, amplifiers and transistor circuit.


This Matlab book with huge examples will be beneficial both for students and teachers who subject is electronics, electrical or telecommunication. The examples provided will help not only students but also seniors to quickly jump to right subject with Matlab. Solution and ideas on electronics circuit important and complex matters such as transistor biasing are provided in the book with codes. The conversion of transistor circuit to AC equivalent circuit are also provided with solutions.

An example of AC frequency response of an amplifier with code and graph is shown below,

%Frequency response of CE Amplifier

rc=4e3; rb1=60e3; rb2=40e3; rs=100; rce=60e3;
re=1.5e3; rl=2e3; beta=150; vcc=10; vt=26e-3; vbe =0.7;
cc1=2e-6; cc2=4e-6; ce=150e-6; rx=10; cpi=100e-12;
cmu=5e-12;

% Ic is calculated

rb = (rb1 * rb2)/(rb1 + rb2);
vbb = vcc * rb2/(rb1 + rb2);
icq = beta * (vbb - vbe)/(rb + (beta + 1)*re);

% Calculation of low frequency poles
% using equations (12.67), (12.69) and (12.70)

rpi=beta * vt/icq;
rb_rpi=rpi * rb/(rpi + rb);
rin=rs + rb_rpi;
wl1=1/(rin * cc1);
rc_rce=rc * rce/(rc + rce);
wl2=1/(cc2 * (rl + rc_rce));
rb_rs=rb * rs/(rb + rs);
rx1=(rpi + rb_rs)/(beta + 1);
re_prime=re * rx1/(re + rx1);
wl3=1/(re_prime * ce);

% Calculate the low frequency zero using equation (12.72)

wz = 1/(re*ce);

% Calculate the high frequency pole using equation (12.74)

gm = icq/vt;
rbrs_prx = ( rb * rs/(rb + rs)) + rx;
rt = (rpi * rbrs_prx)/(rpi + rbrs_prx);
rl_rc = rl * rc/(rl + rc);
ct = cpi + cmu * (1 + gm * rl_rc);
wh = 1/(ct * rt);

% Midband gain is calculated

rcercrl = rce * rl_rc/(rce + rl_rc);
am = -beta * rcercrl * (rb/(rb + rpi)) * (1/(rin));

% Frequency response calculation using equation (12.65)

a4 = 1; a3 = wl1 + wl2 + wl3 + wh;
a2 = wl1*wl2 + wl1*wl3 + wl2*wl3 + wl1*wh + wl2*wh + wl3*wh;
a1 = wl1*wl2*wl3 +wl1*wl2*wh + wl1*wl3*wh + wl2*wl3*wh;
a0 = wl1*wl2*wl3*wh;
den=[a4 a3 a2 a1 a0];
b3 = am*wh;
b2 = b3*wz; b1 =0; b0 = 0;
num = [b3 b2 b1 b0];
w = logspace(1,10);
h = freqs(num,den,w);
mag = 20*log10(abs(h));
f = w/(2*pi);
