Introduction to Op Amps Operational amplifiers (commonly called op amps) are a ubiquitous building block for designing electronic circuits. Today, these devices are fabricated as small integrated ...

Comparing voltage divider performance with and without a 1x amplifier This circuit demonstrates the power of a 1x amplifier. Both voltage dividers produce 2.5V with no load.

A novel full-wave rectifier turns an audio power amplifier into a simple modulator, that is then used to modulate an ...

In the last Circuit VR we looked at some basic op amp circuits in a simulator, including the non-inverting amplifier. Sometimes you want an amplifier that inverts the signal. That is a 5V input res… ...

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 ...

An improved multiple-input op-amp summer can be analyzed more easily than the one in Figure 3. This is because the general design equation can be expressed more simply (Equation 4).
