Open Education Resource: BJT Biasing and
Analysis
About the OER
This OER is from the domain Electrical and Allied (Sub domain: Electronics). The topic selected
for this OER is BJT Biasing and Analysis. It consist of four video lecture (Screen Cast) followed
by quiz, within screen-cast, released under Creative Commons Attribution 4.0 License. It also
provides learning material related to all video in portable data file format. You can watch this video
individually but, it is advisable to watch this video in the sequence given as follows,
Screen Cast 1: Different Type of BJT Biasing Techniques

Learning Objectives
After using this OER, learner will be able to:
Justify the need of biasing if transistor used as an amplifier.
Carry out the DC analysis of Voltage Divider Bias (VDB) circuit.
Justify the presence of components in AC model of transistor and draw it too he
operated at low frequency.
Carry out the AC analysis of CE amplifier.

Section 2: Design Decisions
Nature of Decisions taken
The design decisions involved in the creation of this OER were of broadly three types:
1. Content Decisions
2. Work-distribution based Decisions
3. Technology Decisions
Content Decisions
The content decisions related to:
Finalizing the topic to be covered – Decided on BJT biasing and Analysis
Learning materials to be provided along with screen-cast videos
Work-distribution based Decisions
BJT biasing and DC as well as AC analysis as to be covered. It was decided that each member will
make a screen-cast video on topic related to biasing, DC analysis and AC analysis of Voltage
Divider Bias circuit and the link of these screen-cast was made available in the website specially
made for this OER in word-press.
Technology Decisions
While developing the screen-as video and website for OER, the major technology decisions
taken were:
Tool to be used for creating screencast – Screencast-O-Matic V2.0, as it had a time limit
of 15 minutes and we were well-versed with that.
Word-press for setting up the website wherein all the screen cast video along with
learning materials are made available and hence make it easier for the learner to access
all the materials from the same site.

How to use OER
Screenshots 1-4 shows the page corresponding to various menu available in the website.
Screenshot 1: Home page of website tells the learner about OER: What it is and how to use it.
Screenshot 2: About page of the website tells the learner about the name and qualifications of the
faculties involved in preparing this particular OER. This page also tells about the FDP which
motivated us to make this OER.

corresponding the each screencast video in portable document format.
Best Practices
Please go through the screencast video in sequence as specified in home page of the OER
website.
Quiz have been included in three of the screencast video at the end, so please send your
answer through mail to the email id provided in the screencast video.

Section 4: Evaluating Effectiveness of OER
The OER effectiveness can be assessed at two levels:
1. At the student level
2. At the consumer level
Effectiveness at the student level
Effectiveness at the student level involves metrics related to student access of the resource and
student learning.
The quiz provide in three of the screencast video, if attempted and send to the email as provided
in screencast, helps us to know how effectively the students have learnt.
Effectiveness at consumer level
OER consumers are typically teachers who want their students to learn the BJT biasing and
analysis in simpler form. Linking a survey on three main constructs – Ease of Use, Concept
Coverage and Concept Complexity, can help in identifying the effectiveness of this OER at
consumer level. This has to be done as a follow-up activity.
Implementing Survey
We will send the survey questions to the teacher who tries to contact us through the contact page
of the website or send us a personal mail for commenting on the screencast or asking any doubt.
We would like to have their feedback in terms of following questions.
Survey Questions
1) Ease of Use
2) Concept Coverage
3) Concept Complexity

Section 6: Building a Community of Electronics
Domain
Possible Sources for Community Building
Some of the viable sources for building a community are:
• Teachers who are part of this FDP and of Electrical and its allied domain
• Teachers who plan to use Flipped Classroom Strategies for the topics related to Electronics
