Aims


The aim is to provide an understanding of basic analogue electronics. In
particular, emphasis will be placed on explaining the models behind both the
BJT and the FET devices. Topics covered will include the modelling

and
characterising of basic devices and the exploration of simple circuits such as
rectifiers and single stage amplifiers.

Learning Outcomes

At the end of this module a student should be able to:




Perform small signal analysis of 2
-
port systems for trans
istors



Construct small signal equivalent circuits for transistor circuits



Design a small signal low frequency amplifier using either FETs or
BJTs.



Analyze and synthesize DC bias circuits for transistors



Analyse

and describe the operation of five basic tran
sistor circuits, basic

Penalties:
None, Laboratory Reports must be handed in prior to leaving the laboratory.


Pass Standard and any Special Requirements for Passing Modules
: Pass 40%

students are not
required to pass the written and continuous components separately

Requirements for Autumn Supplemental Examination
: 1x2 hour written examination. The
continuous assessment mark is carried forward to the Autum
n examinations as there is no facility for a
repeat practical examination.



Continual Assessment Results
: Laboratory reports will be corrected within two weeks of submission.
Laboratory reports will be completed in a hard

back notebook, returned to the st
udent for each laboratory,
but must be returned to the lecturer at the end of the module.


Assessment Philosophy

To understand transistor circuits, students require a balance of theoretical knowledge and practical
experience. Analog circuits are not on
-
off devices and it is important to learn the range of behaviours
possible from transistor circuits. This can only be learnt through hands
-
on experience and practical
experimentation.


Therefore considering the desired outcomes, it was decided to place
a strong emphasis on laboratory
work (at 25%) capturing the requirement to be able to construct a circuit and to assess the results of the
theoretical knowledge learned. The remaining outcomes are assessed through an end
-
of
-
year
examination.


The examinat
ion paper is constructed with a compulsory first question and five questions taken from each
of the major topic areas. The compulsory question consists of five parts and ensures that the fundamental
outcomes are addressed by the student in the examination
. The other five questions (of which 3 must be
done) combined into each application space the skills of circuit analysis (DC and small signal),
component performance and circuit architectures.
