Notice how this circuit fits the second rule, though. When the input changes, the op amp makes its output equal because that’s what makes the + and – terminals stay at the same voltage.

We took a look at op amp integrators in the previous article, Op amps do integration, so it makes sense to round out the picture by covering differentiator circuits. Of course, differentiation is the ...

It is by no means a good op-amp by the standards on any era but 1964, as does not have a very high gain, has no short-circuit protection, and requires an external capacitor for frequency compensation.

Question Posed in the Last Issue (Exam Level: CBT) (click thumbnail)In the schematic, what component or components sets the amplifier stage gain? a. The gain is set by the chip itself and can be ...

The traditional inverting op-amp summer configuration exploits the low-impedance node (virtual ground) at the inverting input. The circuit is easy and straightforward to analyze and design with ...

The complete circuit requires eight op amps (two SLG88104 chips), along with a small number of passive components. Due to the phase-sensitive detection ability of the lock-in amplifier, the output ...

Also, the composite buffer in Figure 2 completely eliminates power-dissipation-related errors in the op-amp input.1 C9 and C10 can be replaced by adjustable shunt regulators and R3 and R4 by ...
