This is an in-depth course that takes logic theory and applies it to the analysis, synthesis and simulation of digital logic circuits; and the application and theory of implementing electronics devices. The course also covers the implementation of circuit designs using a hardware description language with specific application to the design of ALUs and simple microprocessors. We also cover the digital assumption made of switching analogue circuits, look at the physical implementation of transistors, circuits based on them and interconnecting components. Assumed knowledge in basic computer architecture and electronics.

Topics covered include:

• Digital Logic: Truth tables, boolean expressions, sets; Boolean logic and manipulation; SOP and POS form; sufficiency; logic minimisation and k-maps; combinational logic; sequential design and finite state machines.
• Computer Architecture: Hardware description language design (VHDL); register specification; adders; arithmetic and logic units; basic execution unit design; integration of design units to build a simple state controller.
• CMOS Implementation of Digital Circuits: Logic thresholds; rise and fall times; noise margins; CMOS inverter; physical implementation on digital characteristics; CMOS fabrication; synthesis of logic in CMOS; effect of capacitance; gate-power prediction, RS flip-flop realisation in CMOS.
• System-on-a-chip: SoC components; interconnects; external chip interfaces; optoelectronic components; photodetectors; lasers; radio frequency devices; RF transistors and diodes.

Learning Outcomes

  • At the conclusion of this course you should be able to:

  • LO1: Represent, manipulate, optimise and synthesise logical expressions for digital circuits using algebraic, graphical, numerical and modelling techniques, hardware description language and associated tools (WA1, WA2)

  • LO2: Design simple microprocessors, including integrating peripheral devices (WA3, WA4, WA5)

  • LO3: Describe, analyse and evaluate the operational characteristics of CMOS (WA2, WA3, WA4, WA5)

  • LO4: Evaluate and optimise the performance of digital electronic devices and components (WA3,WA4,WA5).

  • LO5: Communicate the design of electronic devices to peers in graphical and written form (WA10)
    • University Graduate Attributes

      This course will provide students with an opportunity to develop the Graduate Attributes specified below:

      Critically competent in a core academic discipline of their award

      Students know and can critically evaluate and, where applicable, apply this knowledge to topics/issues within their majoring subject.

      Employable, innovative and enterprising

      Students will develop key skills and attributes sought by employers that can be used in a range of applications.
