Analogue Circuits

Learn electronics online with our summaries of useful analogue circuits, analogue circuit building blocks with essential formulae, calculations, and electronics circuit diagrams.

There is a host of electronic circuit building blocks that can be used. The electronic tutorials in this section provide electronic circuit building blocks along 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 electronic ciruits ranging from amplifiers themselves, through to filters, astables and bistables. Check out these electronic tutorials on operational amplifier circuits.

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.
