Modern cellular phones incorporate hands-free operation, MP3 music playback and DMB reception. The users may wish to use these features for many hours and a low efficiency amplifier could deplete the battery in a short time. There are two classes of power amplifiers usually used for this application: Class-D and Class-AB. Class-D architectures provide the… (More)
This paper presents a class G amplifier based on a low distortion switching principle technique called switching currents injection. The switching circuit enables a very smooth handover between the voltage supply rails obtaining both high efficiency and low distortion. An approach for the evaluation of the switching distortion in a class G amplifier (and… (More)
The electrification of cars is bringing new challenges to the power electronics designers, AC/DC and DC/DC converters are now needed also in the automotive world, car and OEM Manufacturers are striving to address this need in an economical and efficient way.
