Today’s circuit designers usually will need to design with analog circuitry on their boards, even if the core circuitry is Processor-based or a power supply design, MEMS/sensor or such. The problem is ...

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 ...

Editor’s note: We continue with the second part of Chapter 26, Applications considerations and circuits for a new chopper-stabilized op amp. Part 1 of this chapter can be found on EDN online. This ...

The operational amplifier, or op amp, is one of the most basic building blocks used in analog circuits. Ever since single-chip op amps were introduced in the 1960s, thousands of different types have ...

A subject rarely found in circuit design textbooks is the matter of nonlinear junction capacitance, especially reverse-bias junction capacitance, also called depletion capacitance. When it is ...

You think of op amps as amplifiers because, no kidding, it is right in the name. But just like some people say, “you could do that with a 555,” [Doctor Volt] might say, “you can do that with an op amp ...
