Circuits that carry femtoamperes of current have many subtleties that you wouldn’t normally consider in the design and layout of conventional circuitry. If you overlook these subtleties, the circuit ...

Andy recommends favorite resources for basic op amp circuits and includes a portion of TI's AN-20. Test your knowledge with our op amp quiz; answer explanations are included. By 1969, a fledgling ...

In a balanced op-amp circuit, the op-amp inputs see equal impedances looking into the circuit. Balanced circuits provide better performance by cancelling some input errors and have a simple R F /R I ...

Even in today’s digital, IT-intensive radio plant, there is still a need to design and build one-of-a-kind electronic circuits. Simple devices such as digital tone generators and small distribution ...

In electronics, a Norton amplifier—also known as a current differencing amplifier (CDA)—is a specialized analog circuit that ...
