The problem is that if you want a nearly rail-to-rail output by just one-stage amplification, you have to set the amplifier a very suitable DC bias point-- namely, VCC/2 in your scenario.
There is no other solutions except this, especially you input 1Vpp signal and want a 10Vpp output.
But I don't think such dc bias point is good for any practical product.
Anyway, it works at least for your current requirement.
Refer to the book the art of electronics in which there is extremely elaborating explanation of how and why dc-bias point should be set. |
