Carry out theoretical and practical investigations into analogue devices and circuits: Engineering Assignment, NU, UK

Task 1

Carry out theoretical and practical investigations into analogue devices and circuits.
You need to investigate:
(a) Diodes and how they are used in a full-wave rectified power supply with voltage regulation
(b) Transistors and how they are used in a stabilised common emitter amplifier
(c) Operational amplifiers and how they are used in an amplifier circuit

You need to provide evidence that you have consistently worked safely in accordance with relevant
risk assessments.
To do this you will need to work systematically following the guide below:
(a) Diode circuits
(i) Identify different types of diodes and their uses
(ii) construct a schematic diagram and simulate the operation of a diode as a half-wave rectifier
(iii) develop the circuit schematic and simulation to a full- wave rectifier with capacitor smoothing and Zener diode voltage regulation.

iv) build a prototype of your final circuit
(v) record the output voltage
(vi) estimate the voltage ripple for different loads
(vii) compare the results from theory, simulation and measurement
