Description

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:

1. 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

2. Computer Architecture: Hardware description language design (VHDL); register specification; adder design; ALU design; basic execution unit design; integration of design units to build a simple CPU

3. 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

4. System-on-a-chip: SoC components; interconnects; external chip interfaces; optoelectronic components; photodetectors; lasers; radio frequency devices; RF transistors and diodes; power microelectronic devices

Learning Outcomes

  • At this end of this course students will be able to:
  • Understand and apply Boolean algebra including:  de Morgan's theory, sufficiency, SOP and POS form.
