Circuit Design
Learn electronics online with our summaries of useful circuits, circuit building blocks with essential formulae, calculations, and electronics circuit diagrams.
There is a host of electronic circuit building blocks that can be used. There are many circuits and circuit ideas in this section that have been gained from many years as an engineer working in a development laboratory.
The circuits can be used to provide the electronic circuit building blocks required within many electronic circuit designs. Also the circuits are come with with design information, formulas, practical hints and tips where applicable and useful guides on the electronic circuits.
Transistor circuits
Despite the fact that integrated ciruits are widely used today, electronic circuits using discrete transistors can still provide excellent performance.
Operational amplifier circuits
Operational amplifiers provide an ideal basis for a large number of analogue electronic ciruits ranging from amplifiers themselves, through to filters, astables and bistables.

Power supply circuits
Power supplies and the electronics within power supplies are very important. Without them many electronic circuits would not work, and it is also important to ensure the specification of any power supply meets the requirements of the circuit it is powering.
Electronic circuit design standards and design aims
There are several areas that need to be borne in mind when designing electronic circuits and equipment. They range over a variety of areas.
