"大家都喜欢这个电路,能不能帮忙分析一下这个电路?"
it is fairly simple.
for the original poster's schematic, tr1/tr2 is fronted by a signal conditioning network. tr1/tr2 forms the differential pair. tr3 is a constant current source.
tr4 is the voltage amplification stage. tr4's load is a constant current source (tr6).
tr9/tr10 are the drivers, and tr11/tr12 are the output devices. Vbe multipler is tr5.
as simple as that. |
