Carissa Sipp, Systems Engineer, brings us this session. Fully differential amplifiers (FDAs) are versatile tools to use in a signal chain, and they offer a variety of benefits. Fully differential ...

The following is Part 1 of a four-part series. The basic one-op-amp differential amplifier consists of one op-amp and four resistors. Yet few have contemplated the depth of its complexity. It is ...

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 ...

This basic differential amplifier, while appearing not very complicated, is unconventional in that it operates the EPAD MOSFET devices in the subthreshold region. Therefore it requires a different ...

If you’re the sort who finds beauty in symmetry – and I’m not talking about your latest PCB layout – then you’ll appreciate this clever take on the long-tailed pair. [Kevin]’s video on this topic ...
