EEEN20050 Digital Electronics: from gate to system

Academic Year 2022/2023

Digital electronic circuitry forms the heart of virtually all complex electronic systems. This course teaches basic concepts of digital logic gates and looks at building blocks of digital systems.

Topics include:
- Binary systems: logic gates, Boolean algebra;
- Combinational circuits: simplification of combinational expressions, arithmetic circuits, control circuits, multiplexers and decoders;
- Sequential circuits: flip flops, registers, counters, synchronous state machines, memory circuits, configurable logic, FPGAs;
- Implementation technologies and performance metrics: Bipolar transistor logic families, CMOS logic, timing considerations in both synchronous and asynchronous systems.

The laboratory component of the course provides an opportunity for development and testing of circuits encountered during the course through simulation software. Labs will focus on the development of modular subsystems and the interconnection of these subsystems in design exercises.

Learning Outcomes:

On successful completion of this module, students should be able to:
- Use and explain the different ways of representing unsigned and signed rational numbers e.g. decimal, binary (unsigned, sign and magnitude, one's complement and two's complement), and hexadecimal; the advantages and disadvantages of each of these number systems, and how to convert numbers between them.
- Write Boolean algebraic functions that desribe a given system or circuit, and simplify this system using Truth Tables and Karnaugh maps.
- Perform binary arithmetic, and explain the digital circuits that perform these arithmetic operations.
- Analyse the operation of synchronous and asynchronous digital circuits and subsystems, using state equations, state diagrams, and transistion tables.
- Design a synchronous digital circuit to meet a given specification.
- Understand the digital system design flow using CAD tools, and work in a team to finish a small-scale project.
- Explain how digital systems communicate with each other and with their external environment, discuss the factors that limit the performance of digital systems e.g. timing issues, fan-out limitations etc.
