Microchip has announced the third generation of its dsPIC33EP ‘GS’ range, which are DSP-enabled microcontrollers. GS denoted devices specifically intended for fast digital power supplies, which need ...

The performance of analogue phase-locked loops (PLLs) has steadily improved with operating frequencies extending to 8GHz and beyond. Recently, digital PLLs based on direct digital synthesis (DDS) have ...

In telephone communications, a technology that increases the number of channels in the local loop by converting analog signals to digital and multiplexing them back to the end office. Digital loop ...

I recently heard a claim that at the output of a power converter, digital and analog loop are the same. The claim went like this: “a power supply using digital power control techniques will appear ...

This article presents loop stability analysis in analog and digital feedback systems. It presents finding the analog loop stability experimentally and by using Laplace transform, as well as finding ...

Application flexibility and cost concerns are creating a demand for intelligent power-supply designs that support soft configuration in production and external control. These advanced power supplies ...

Today's microcontroller units (MCUs) can implement the control functions and feedback loops of off-line ac-dc power converters, which do not require extremely fast control loops. As an example, a ...
