Course content
Approximation to nonlinear characteristics, analysis and synthesis of nonlinear resistive circuits,
harmonic analysis of nonlinear dynamical circuits, transient states in nonlinear circuits, application of
computers in the analysis of linear and nonlinear circuits; Active filter synthesis:- the filter
approximation problem, design of filters based on the Sallen – Key approach, multiple feedback
configurations; gyrators, Negative impedance converters (NIC) and frequency dependent negative
resistors.
Course Objectives
The objectives of this course are to:



Introduce the concept of nonlinearities in general and how they occur in electrical and
electronics components in particular;
Outline and develop several approaches on how to analyze and synthesize circuits with
nonlinear components
Introduce the concept of frequency selectivity in electrical and electronics systems and the
methods available for dealing with such problems using filters and filter types; and

Treat filter synthesis techniques and the design of analog active filters using OpAmp based RC,
the Sallen – Key realization and the substitution techniques using specialized components such
as the gyrator and NICs.
A good foundation in this course will provide the tools that an electronics or communications engineer
will require in order to either maintain, adapt or design systems in the field. The techniques here also
can become the foundation for the extension of the students’ capability to address some real-life
problems that do not conform to the linear framework that constitutes the study environment.
Course Justification
This course is essential for providing the students with the basis for the design and application of one of
the most ubiquitous elements in electrical, electronics and computer systems. Familiarity with the
concepts hereby addressed constitute an important component of the finished electrical and
information engineer’s toolkit.
Grading
The grading includes a final examination that carries 70% of the course grade and a continuous
assessment of 30%. The continuous assessment consists of two tests, several assignments and a
simulation and design exercise.
Delivery Strategies
The methods for lecture delivery includes:
 Lecture delivery using power point centric presentations provided ‘a priori’ to each student and
available on individual systems (laptops and tablets) as well as a multi-media projection system;
 Tutorial problems and tutorial and workshop sessions when students are brought into contact
with real problems illustrating the concepts being addressed; and
 Feedback through questions and answers by students via the intra-net and internet to further
improve contact and access the information.
Modules
The course is divided into …. Modules corresponding to a series of lectures as follows:
 Module 1
Revision of the basic mathematics required to comprehend the course and a review of the
concepts of two port electrical networks;
 Module 2
Nonlinearity as a concept and tests of nonlinearity in device characteristics and types of
nonlinearities; Graphical representation of nonlinear characteristics and separation of nonlinear
circuits into linear and nonlinear blocks; Graphical solution of nonlinear systems in electronics –
concept of the load line. Small signal analysis techniques for linear signal applications.
 Module 3
Numerical solution of nonlinear equations by computer methods – fixed point, midpoint,
Newton – Raphson and secant approaches; algorithms in EXCEL and MATLAB for realizing such
solutions.
 Module 4
Introduction to Filters, types of filters and quantitative conditions for the realizability of given
driving point impedances; synthesis of filters using Foster and Cauer methods for loss-less
filters; Active filter realizations using gyrators and capacitors;
 Module 5
Introduction to OpAmp based RC filters; Sallen-Key and multiple feedback configurations for
filters; Design of practical filters using Sallen-Key configuration. Use of Computers for the design
and realization of basic active filters; Introduction to industrial type specialized active filter
modules.
 Module 6
Workshops involving hands-on use of individual computers for solving individual applications for
nonlinear circuit design with small signal applications, solutions of nonlinear networks by
iterative techniques, approximation techniques; Realization of Sallen-Key filters and a study of
sensitivity to component tolerances.
