Improved Diamond Buffer Design - diyAudio
2008年10月6日 · Hi All I was wanting to build a discrete buffer for a preamp/headphone amp, so I started with a classic diamond buffer design and I found that I had to increase the bias to drive the low impedance loads at low distortion, but then the …
How to compensate bias current of Output Error Correction?
2021年11月17日 · Using a diamond buffer like you do would allow to mostly cancel two Vbe of the quad by thermally coupling Q3+Q7 / Q4+Q8. Clever idea. I would probably put them on an extra radiator. As previous posters explained, Q9 and Q10 can be used for sensing. Usually, R14 is used to set the bias.
Diamond Buffer variations - diyAudio
2021年10月16日 · The issue with diamond buffers is driving the output devices. If bipolars, their base demand can exceed the capacity of the first stage, and so the best option is the diamond buffer/CFP buffer in the second example. You don't need current to drive mosfets, but they have hungry, capacitive gates, and they reduce the rail efficiency.
