A fully differential class AB two-stage op-amp with and without common-mode feedback circuit (CMFB) are proposed. There are 4 schematics to be proposed. The first schematic is CMOS complementary input ...

For the data drivers of TFT-LCDs with high gray-scale above 8-bit, OP-Amps with high voltage accuracy less than 1 mV, is needed. Accordingly, the offsets voltages of the OP-Amps should be compensated ...

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

Whether you want a desktop DAC and Headphone Amplifier for listening to music or modernising a hi-fi system, the new Topping DX5 II is now shipping.

Once past the basics of Ohm’s Law and the schematic diagram of a single-ended op-amp set for a gain of 100, I would go into ...

The global amplifier and comparator market reached a valuation of approximately USD 5.25 billion in 2025 and is anticipated ...

As autonomous AI agents increasingly influence decisions in critical domains—healthcare, finance, governance, and more—the ...

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

The future for monolithic amplifiers indeed looks bright. However, there are many areas in which substantial improvement over present-day devices is needed. Foremost among these are the requirements ...

India will send the severely damaged black box from the Air India Boeing 787 crash to the United States for detailed analysis ...

To see why, we’ll dive back into the theory of operation of the op amp, considering closed-loop response compared with open-loop response. If you want an audio pre-amp circuit using an op amp with a ...
