以相同面積來說npn本身結構Q值上比pnp還要差 如果再加上mismatch的影響 不在乎精準度可以用npn
This beta mismatch creates an offset current that is reflected back to the input stage and creates a systematic voltage offset. One controllable current source is provided for each of the top side and the bottom side of the input stage, and each current source, sources/sinks a current of a...

A fully symmetrical class AB amplifier includes two controllable current sources in the input stage to compensate for NPN, PNP transistor beta mismatch. This beta mismatch creates an offset current that is reflected back to the input stage and creates a systematic voltage offset. One controllable cu...
