Ericsson POL regulators are implemented by using non-isolated synchronous buck topology shown in Figure 1. During normal operation of a buck power stage, QH and QL are alternatively switched on and ...

Part of the designer's average 'EMI troubleshooting day' may involve taking a core from the shelf and just winding some turns on it. But what if he is really struggling to bring up the inductance and ...

Many sensors have a small analog signal that rides on top of a larger dc pedestal. For these circuits (Fig. 1), the signal must be ac coupled and amplified before it’s digitized. The feedback of an ...

Today's analog system designers face many design challenges. Not only do designers need to select the proper integrated-circuit components, but they also must accurately predict the interactions of ...
