Unit Information

This unit deals with a broad and essential range of topics in analogue electronics at an intermediate level. It covers the design of circuits using MOSFET and BJT devices, the effects of feedback, the design of high power amplifiers, and the operation of oscillator circuits.

Elements:

Bipolar Junction Transistors (BJT): BJT Operation, npn and pnp transistors in active mode, analysis of transistor circuit at DC, BJT as an amplifier, small signal equivalent circuit model (the hybrid-pi model, the T model and graphical analysis), BJT discrete circuit design, basic BJT amplifier configurations.

MOS Field Effect Transistors (MOSFET): MOSFET as an amplifier, small signal model, MOSFET discrete circuit design, single stage MOSFET amplifiers, multi-stage amplifiers (differential pair current mirror and cascode).

Feedback: Open and closed loop gain, negative feedback (effect on gain and bandwidth), basic feedback topologies (voltage, current, transconductance and transresistance), analysis of gain, input and output resistance of series-shunt, series-series, shunt-shunt and shunt-series feedback amplifiers.

Output and Power Amplifiers: Classification of output stages, class A, B and AB output stages, biasing analysis of class AB stage.

Oscillators: Principles of sinusoidal oscillators, RC oscillator circuits (Wien-Bridge and Phase shift oscillators), LC tuned oscillator (Colpitts).

Your learning on this unit

On successful completion of this unit, students should be able to:

  1. describe the operation of a BJT and carry out the associated DC circuit design.
  2. apply small-signal models such as the hybrid-pi and the T-model to analyse the performance of single stage circuits.
  3. describe the operation of the MOSFET and carry out associated discrete DC circuit design.
  4. describe the basic concepts of MOSFET-based multi-stage amplifiers such as the differential pair, and cascode.
  5. describe the different amplifier output stages (A, B and AB) and be able to carry out basic biassing of a class AB stage.
  6. describe the general principles of sinusoidal oscillators and be able to analyse and design simple oscillators based on RC and LC circuits.

How you will learn

Teaching will be delivered through a combination of synchronous and asynchronous sessions, including lectures, practical activities supported by drop-in sessions, problem sheets and self-directed exercises.

How you will be assessed

Formative: Lab Report & Online Test 1&2

Summative: Exam (January, 100%)

Resources

If this unit has a Resource List, you will normally find a link to it in the Blackboard area for the unit. Sometimes there will be a separate link for each weekly topic.

If you are unable to access a list through Blackboard, you can also find it via the Resource Lists homepage. Search for the list by the unit name or code (e.g. EENG26000).

How much time the unit requires
Each credit equates to 10 hours of total student input. For example a 20 credit unit will take you 200 hours of study to complete. Your total learning time is made up of contact time, directed learning tasks, independent learning and assessment activity.

See the Faculty workload statement relating to this unit for more information.

Assessment
The Board of Examiners will consider all cases where students have failed or not completed the assessments required for credit. The Board considers each student's outcomes across all the units which contribute to each year's programme of study. If you have self-certificated your absence from an assessment, you will normally be required to complete it the next time it runs (this is usually in the next assessment period).
The Board of Examiners will take into account any extenuating circumstances and operates within the Regulations and Code of Practice for Taught Programmes.
