Rationale and Purpose of the Module:

- To introduce the student to the physics of solid state electronic devices and to their application - To introduce the student to semiconductor devices, electronic logic and digital devices

Syllabus:

Conduction in solids: elementary band theory of conductors, semiconductors and insulators, doping; donor and acceptor impurities, intrinsic and extrinsic conduction, majority and minority charge carriers. The PN junction: junction diode and applications, Zener diode, the bipolar transistor; transistor action, applications - the emitter amplifier, early effect; the field effect transistor, JFET, MOSFET, characteristics and application in simple circuits. Combinational Logic: Binary Logic, Logic functions; AND, OR, NOT; Truth table; Boolean Algebra; Boole Boolean postulates and theorems, De Morgan; Logic gates - complete set; NAND and NOR implementations of logic functions; Multiple-input gates. Sequential Logic: Memory, feedback, synchronous/asynchronous, Flip-flops, Latches; basic SR latch, gated SR Latch, D-type, Master-slave latch, JK Latch; Shift Registers, Counters, UART (block diagram). Operational and Instrumentation amplifiers: desirable characteristics, comparators, voltage reference, virtual earth, voltage follower, Nyquist-Shannon sampling theorem.

Learning Outcomes:

Cognitive (Knowledge, Understanding, Application, Analysis, Evaluation, Synthesis)

How to measure and encode information in various digital formats. Basic and combinational logic components, design, analysis and implementation of combinational logic circuits. The principles of sequential logic, memory elements and simple sequential circuits. How to design circuits for instrumentation and measurement. Derive relevant equations from basic laws and principles. Solve numerical problems, from information provided, on the topics covered

Affective (Attitudes and Values)
