FiiO is taking the entry-level fight to WiiM’s door this week with the introduction of the K15: a desktop streaming DAC ...

Here’s a nostalgic vibe of an awesome analog chip from the 1990s era that’s still making an impact in audio designs.

MIT scientists have built a tiny, ultra-efficient 5G receiver that can thrive in noisy wireless environments ideal for smartwatches, wearables, and sensors that need to sip power and still stay ...

These amplifiers cover 1.8GHz to 4.1GHz, with available power levels of 40W, 60W, and 80W.

ISSCC, the International Solid-state circuits conference, is the IEEE’s annual showcase for all that is best in on-chip circuit design from across the globe. Thousands of engineers will flock there ...

The stacked-device power-combining technique is a proven method to increase the output power and load impedance of a power amplifier (PA) simultaneously. The series-input configuration is physically ...

Elektor has a long history of presenting innovative amplifer designs. Combining a classic Class-B design with short-circuit protection and up to 50W output, this durable power amplifier from 1994 is ...

In a Class A circuit the level of that current is always set to maximum. If that amplifier design is working at full volume then the bulk of that energy is used to drive the speakers. (Note that no ...

They are just a convenient way of differentiating types of amplifier circuits. For example, “D” does not stand for “Digital” in a Class D amplifier, although there seems to be some conflicting ...

Class AB Amplifier The main class AB advantage is that it has the lowest distortion—total harmonic distortion plus noise (THD + N) is less than 0.1% for high fidelity. The main disadvantages are that ...
