Hi,
I have designed two-stage Miller compensated (MC) amplifier, then i would like to use it as a high gain non inverting amplifier. Note that this amplifier should have just a single input, how can i use multi stage of the proposed amplifier to achieve an amplification stage of a single input and single output.
The picture of this amplifier is given as below. I'm so grateful to help me.

Biasing circuit(s) are not drawn so how this amplifier will work as you've designed as ?
If V- Input is AC grounded, it will work single-ended amplifier but pay attention frequency response and stability.
You have to use negative feedback, than you can combine inverting amplifiers or non-inverting amplifiers.
Optimal design depends on how much gain and bandwidth required for the multistage amplifier, how much is the DC offset of 1 stage.
You have to be more specific, share more parameters, results, the application than we can help maybe.
