Op amps are highly compact electronic components, often with hundreds of internal transistors packed onto the die. To illustrate the complexity of a typical op amp, refer to Figure 2, which is the block diagram of the internal architecture of many (but not all) op amps that use a four-sta...
Yes, but all capacitors are bad, so we'll make a rod for our backs and use another op-amp to make a servo to force first op-amp to do what it really didn't want to (this part not shown in diagram). Regarding the "which way up?" comment on my last diagram, it depends on wh...

The op-amp’s most important functional block is a differential amplifier. It is appropriate to say thatop-ampis nothing but a differential amplifier with a very high gain. Hence thesymbol for an op-ampis the same symbol that we use to represent a differential amplifier. The following symbol...
Figure 1. The MAX40007 nanoPower op amp is available in ultra-tiny WLP and SOT23 packages. As an example end application, consider the portable patient monitoring design shown in Figure 2. To the left of the processor, in the signal chain block, two op amps are used to filter the signal...

Op Amp Error SourcesFigure 1 shows a simplified op amp block diagram with ac and dc error sources added. The topology is a single-pole amplifier with an input gm that drives a gain node that is buffered as the output. While there are many op amp topologies, the error sources shown ...
