Circuit simulations are great because you can experiment with circuits and make changes with almost no effort. In Circuit VR, we look at circuits using a simulator to do experiments without having to ...

Operational amplifiers (commonly called op amps) are a ubiquitous building block for designing electronic circuits. Today, these devices are fabricated as small integrated circuits, but the concept ...

Fig 1. An op amp easily accomplishes addition, while a Gilbert cell handles the task of multiplication.caption of image Fig 2. Two digital words are added by combining a series of full adder cells.

It’s been a running battle in some quarters for years, whether analog sensor processing is better than digital. Proponents of digital are sometimes driven by lack of familiarity with analog circuitry, ...

According to ROHM, its ultra-compact TLR1901GXZ CMOS op amp is the industry’s lowest operating circuit current. The op amp is built to be used as a measurement-sensing amplifier in space-constrained ...

Moreover, the TLR1901GXZ features an exceptionally low input offset voltage of just 0.55mV (max.), one of the best among ultra-low current op amps. A maximum input offset voltage temperature drift of ...

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 ...

b. The gain is set by VCC as the higher the supply voltage, the higher the gain. c. By the value of R3 as this resistor to ground sets the offset bias seen by the op-amp hence the gain. d. By the ...

Design analysis of the K2-W Vacuum Tube Op Amp’s design and operation reveals the mad science that created a commercial revolution in 1950s and 1960s analog computing. Op amps played a critical role ...
