The difference amplifier is a common and useful circuit employed in various applications ranging from factory automation to electric vehicle systems. That’s primarily because it’s helpful to add ...

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 ...

Although current-feedback operational amplifiers (op amps) have been on the market since the 1990s, the current-feedback fully differential amplifier was not introduced until 2007. There are several ...

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 ...

Accurately measuring current flow is a standard requirement in several applications (Fig. 1). Depending on the specific need, the options available to designers can include discrete designs assembled ...
