Our emphasis in this course is on semiconductor devices based circuits.
Semiconductor Devices:
Diodes
Bipolar Junction Transistors (BJT)
Field Effect Transistors (FET)
the semiconductor electronic devices can be used singly along with
resistors, capacitors and inductors
for the design of discrete circuits.
Or as components of an integrated circuit (IC) chip
Integrated Circuit(IC)
An integrated circuit (IC) has multiple electronic devices (diodes or
transistors) in a small piece of silicon (or any other semiconductor).
e.g. A microprocessor has hundreds of millions of components in a small
piece of silicon whose area is on the order of 100mm2
Diodes
A Diode
is a two terminal device
is the most fundamental non-linear circuit element
The Ideal Diode

from the i-v characteristics of the ideal diode,
one can see that the diode can operate in two distinct modes
either as a Reverse Biased Diode
or as a Forward Biased Diode
Reverse Biased Diode
If a negative voltage 'v' is applied to the diode,
no current flows through the diode
the diode behaves as an open circuit
and the diode is said to be cutoff
Forward Biased Diode
If a positive current i is applied to the ideal diode,
zero voltage drop appears across the diode.
i.e. the diode acts as a short circuit in the forward direction
the diode will pass any current with zero voltage drop.

, Handout 1 , Asst Prof M Anis Ch, Electronic Devices and Circuits
The external circuit must be designed to limit
the current through the conducting (forward biased) diode
the reverse voltage across a cut off (reverse biased) diode
