    Hi everyone
    I need to design an error amplifier for an LDO in umc 65nm technology. I have read lots of papers about it but still don't know where to start and how to reach my specifications:confused:.Any body has any hints for me?

    Input+error=Output
    error=Output-Input
    So.
    Take input signal, split it into two signals, Signal 1 and Signal 2.
    Signal 1 goes into the circuit that produces output. Take the output and feed it into Difference Amplifier.
    Signal 2 goes into Difference Amplifier.
    Now you have original input signal (Signal 2) and output signal going into difference amplifier, the result is the amplified error.

    No idea what 65 nm has to do with it. That something you will have to figure out.

    Thanks for your help.But here is videos I found on youtube. This explains the design process in 180nm for a usual amplifier. But I'm not sure if I can use the same procedure
