Analogue Electronics

This unit introduces operational amplifiers as a major building block of analogue electronics. The ideal op-amp model will be covered and the fundamental op-amp circuits discussed, e.g single ended amplifiers, differential amplifiers, integrators and differentiators, summing and instrumentation amplifiers. The non-ideal characteristics of the op-amp such as saturation, input offset voltage, input bias currents, finite open loop gain and finite gain bandwidth will then be covered. The final part of the unit introduces semiconductor discrete devices at an introductory level. These include for example, zener diodes, BJTs and MOSFETS. Examples of practical issues, such as biasing and amplifier configuration will be covered from the perspective of a single device type i.e. selected from either BJT or MOSFET.
