Trying to get a circuit to sense its own current consumption can be a little tricky. That said, there are plenty of specialist three and four terminal chips that will sense across a resistor in the ...

The op amp-based current sensing circuit described here is not new, it has been around for some time, but with very little discussion of the circuit itself. Somewhere along the line it was informally ...

Battery management encompasses two main functions: 1. Charging adapter, and 2. Battery fuel gauging and protection on the battery side. The block diagram in Figure 1 depicts the overall system. In ...

Figure 5: A simplified circuit diagram of a Hall Effect sensor that integrated the current conduction path. The integrated conduction path (IP+, IP-) has a resistance ranging from 0.1mΩ to 2mΩ. The ...

There are different methods to sense and measure current inside a circuit or a conductor. In this article, we will discuss how to measure current using various current sensing techniques with their ...

These circuits have been culled from a variety of Linear Technology documents. Circuits Organized by General Application Each chapter collects together applications that tend to solve a similar ...

High-side current sensing gets a lot of attention, but that doesn’t mean low-side sensing should be ignored.

How did I miss this current sense curcuit? Seeking something-or-other, I came across a high-side current sense circuit that I had never noticed before. Here it is (right), in an app note for the ...

A novel on-chip current-sensing technique, which is suitable for a current-mode control CMOS DC-DC buck converter, is presented in this paper. The proposed current sensing circuit doesn't need an op ...
