A few years ago, I was working on the design of a data acquisition system (DAS) that would eventually need to be tested when manufactured. It had both high-side current sensing and floating diff-amp ...

Amplifier circuit offsets are always an important topic for any amplifier design. Most voltage amplifier circuit offsets are a result of the amplifier’s input voltage offset, input bias current and ...

It isn’t unusual to expect a precisely regulated voltage in an electronic project, but what about times when you need a precise current? Over on EDN, prolific [Stephen Woodward] explains how to use a ...

PMOS transistors are less vulnerable to substrate noise since they’re placed in separate wells; designers implement guard rings to attenuate the substrate noise propagation. However, substrate noise ...
