We note, however, that Marantz hasn’t leapt to GaN for its high-end amplifiers, and in a recent online briefing the team indicated that it considers the Purifi ‘Eigentakt’ circuits used in its recent ...

A transimpedance amplifier for optical communication system is presented in this study. The design includes a regulated cascode and an interleaving active feedback to improve the bandwidth of the ...

The differences between the Marantz and the WiiM might also come down to a matter of perspective. I see the Stereo 70s as an integrated amplifier with an internal DAC and streaming front end, but I ...

FiiO is taking the entry-level fight to WiiM’s door this week with the introduction of the K15: a desktop streaming DAC that’s also a pre-amplifier and a powerful headphone amplifier. Suffering a case ...

Operational amplifiers play a major role in analog and mixed signal integrated circuits. This paper proposes flexible and high throughput 4 -stage operational amplifier designs.
