Frederik Dostal explains the rise of the ideal diode and how it can be used to develop more robust power systems.

Author Mazi Hosseini describes a simple, low-cost, voltage-controlled current source using two op amps that provides a good range of current and maximum load. One challenge in circuit design is ...

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 ...

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 ...

The input offset voltage (V OS) of an operational amplifier (op amp) is modeled as a DC error source that acts like a voltage source on the noninverting input. It can ...
