The design of a switching power supply has always been considered a blend of magic and art by every engineer that designs one for the first time. Fortunately, today the market offers different tools ...

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 ...

In my May blog post, I described the construction of a low-pass filter that used op-amps, capacitors, and resistors. I ignored thermal drift, long-term accuracy, and other characteristics and tested ...

Almost all off line switching power supplies over several kilowatts of output power use a three phase bridge rectifier. Typically, it comprises a six diode bridge and a DC bus filter capacitor. A ...

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 ...
