This module introduces basic microcontroller structure and operation. It consists of a lecture course on the architecture and operation of the target microcontroller, and a series of laboratories culminating in a mini-project in which students will apply their experience to a simple practical problem.
The module covers aspects of Engineering Applications for Level 1 students and all aspects of the design process for analogue circuits. It includes preparation, performance and reporting on a structured series of experiments supporting the taught modules at this level and gives practice in using IT packages to assist with report writing.
This module introduces circuit elements such as transistors and FETs and shows how they can be used as amplifiers and switches.The amplification and bias conditions for transistor amplifiers are analysed and discussed in detail. Circuit elements necessary for building operational amplifiers such as the long tailed pair and the current mirror are analysed, and a complete circuit for an operational amplifier is discussed. Some applications of operational amplifiers such as the function generator and instrumentation amplifier are introduced with practical applications. Circuits using MOSFETs for logic and analogue switches are described.
The module is intended to reinforce aspects of Engineering Applications (EA1) and develop EA2. Advanced features of microcontroller operation are introduced, including interrupts and programming of features of the selected microcontroller. Extended experimental work is carried out as a Group Design Exercise. Practice in using technical IT packages including microcontroller software development and the use of design aids such as PCBs and engineering drawing is inherent. Development of project documentation through a web-site. Concepts of engineering ethics introduced in first year are developed through a formal lecture, and examined as part of the presentation in the final assessment.
The huge range of electronic devices available today are based on a limited number of circuit elements. For example, cellular mobile telephones use basic circuits such as oscillators, frequency synthesisers, frequency selective circuits, in addition to sophisticated digital components. In this module, some of the key circuits are identified and discussed, including analogue multipliers, frequency selective networks, frequency synthesisers, and ADC/DAC techniques.
The laboratory modules EGA222 and EGA223 provide a practical experience of some of the material presented in taught modules, including EG-240 Electronic Circuits, EG-241 Electrical Machines, EG-247 Signals and Systems. Experiments on Amplitude Modulation, Frequency Modulation and Digital Modulation are also included to support the two Communications modules later in the degree programme.
